The ten largest refiners include both companies that mine and refine their own zinc ores, as well as refiners that purchase from independent mines. In many cases, refiners use both their own and sourced zinc ore supplies.

Founded in 1974, Korea Zinc Co. Ltd. is Korea's largest non-ferrous metals company and the world's largest producer of zinc. The company refined 610,000 tons of zinc in 2017, or about eight percent of global zinc production when including its sister company and subsidiary. The applications for zinc include autos, galvanized steel, and machine parts.Besides zinc, Korea Zinc is also a major refiner of lead, copper, gold, indium, nickel, bismuth, gallium, and cadmium.

Producing over 1 million tons of zinc in 2017, Nyrstar accounted for over seven percent of global refined zinc production. The company's largest refineries include the Balen smelter in Belgium, the Budel zinc plant in the Netherlands, and the Hobart smelter in Australia. As of Q3 2018, Nyrstar's zinc production rose by 4% for the first nine months when compared to the first nine months of 2017.

Incorporated in 1966, Hindustan Zinc Limited operates one of the world's largest zinc mines with annual production over 840,000 tons.TheChanderiya Smelting Complexhas the capacity to produce 535,000 tons of zinc.The company's smelters are located in Chanderiya, Debari, and Dariba.

Formed with the merging of Glencore plc with Xstrata in 2013, Glencore Xstrata (now known as Glencore) is the world's largest miner of zinc ores. In 2017, the company mined over 1,090kt of zinc from facilities in Asia, North America, Europe, and South America.The company has a 69 percent stake in Kazzinc, Kazakhstan's largest zinc producer.

Former Brazilian mining company, Votorantim Metais became Nexa in 2017. Nexa ownsand operates the Cajamarquilla Zinc Refinery in Peru, which has a production capacity of over 300,000 tons of zinc per year.In 2017, Nexa produced 570kt of refined zinc.

In 2017, Boliden produced over500kt in zinc as the 6th largest zinc producer in the world. Boliden Tara in Ireland is Europe's largest zinc mine and has mined more than 85 million tonnes of ore since 1977.

Shaanxi Nonferrous Metals is China's largest zinc refiner. Its core zinc operations are managed by Hanzhong Zinc Industry Co. Ltd., located in Mianxian County, Shaanxi Province, and Shaanxi Zinc Industry Co. The Mianxian mine produced 472kt of zinc in 2017, making it the sixth largest zinc producing mine that year.

The state-controlled Chinese metals producer China Minmetals Corp. isChinas biggest and most international metal ore mining company is headquartered in Beijing. With mines inAustralia, South America, Africa and other parts ofAsia,China Minmetals is involved in the production of virtually every metal, including copper, aluminum, tungsten, tin, antimony, lead, zinc, rare earths, and nickel.

Noranda Income Fund is an income trust that owns the electrolytic zinc processing plant in Salaberry-de-Valleyfield, Quebec. According to the company's website, the Processing Facility is the second-largest zinc processing facility in North America. The facility is operated and managed by Canadian Electrolytic Zinc Limited, a wholly-owned subsidiary of Glencore Canada Corporation.

The no. 3 and 4 spots are both occupied by Glencore operations in Australia: Mount Isa Zinc and McArthur River. The giant Antamina mine in Peru dropped two spots to no. 5 after seeing its output plunge over 25% to 255.6kt last year.

fireweed zinc commences 2021 drill program at macmillan pass - junior mining network

fireweed zinc commences 2021 drill program at macmillan pass - junior mining network

VANCOUVER, British Columbia, July 06, 2021 (GLOBE NEWSWIRE) -- FIREWEED ZINC LTD. (Fireweed) (TSXV: FWZ) is pleased to announce that the 2021 diamond drill program has started at the Macmillan Pass zinc-lead-silver project, Yukon, Canada.

Brandon Macdonald, CEO, stated We are excited to get drills turning again at Boundary Zone and especially at the new Boundary West discovery from late last season. This drill program will allow us to both further test the extent of the main zones of mineralization as well as explore the potential of new targets. The planned drilling will allow us to prove up our new discovery and step-out on known zones which still remain open for expansion.

The diamond drill program has begun with the first holes targeting step-outs around the 2020 discovery, Boundary Zone West, 300 m to the west of Boundary Zone. Drilling highlights from 2020 include Boundary Zone West hole NB20-004, which intersected 76.5 m of 4.22 % zinc (Zn), 0.34% lead (Pb), and 25.6 g/t silver (Ag) including 24.1 m of 6.46% Zn, 0.77% Pb and 47.5 g/t Ag within 90 m vertical depth from surface (see Fireweed news releases dated February 3, 2021 and February 25, 2021).

Zinc-lead-silver mineralization in the Boundary Zone area occurs in several styles, including: high-grade stratiform barite-replacement similar in style to mineralization seen at Tom and Jason; sphalerite-pyrite-galena veins and high grade breccias; and stratiform zinc mineralization in the same age host rocks as the giant Howards Pass deposits. Zinc mineralization has been demonstrated over approximately 2 km in strike from previous historic and Fireweed drilling. The diversity in mineralization styles and the large area endowed with zinc mineralization suggest that Boundary Zone formed as part of a long-lived hydrothermal system that experienced multiple pulses of mineralization. Drilling at Boundary Zone and Boundary West will comprise step-out holes to better understand the grade, geometry and continuity of mineralization within what already appears to be an extensive hydrothermal system.

Two drill holes are planned at Tom East, a high-grade zone with a current Mineral Resource of 0.81 Mt at 8.74% Zn, 8.62% Pb, and 110.0 g/t Ag Indicated Resource in addition to 1.68 Mt at 9.86% Zn, 12.86% Pb and 170.0 g/t Ag Inferred Resource (see Fireweed news releases dated January 10th, 2018, and reports filed on www.sedar.com for details). In 2018, Fireweed drilled a very-high grade step-out hole at Tom East in an area outside of the current Mineral Resource, intersecting 16.41 m of 21.1% Zn, 13.5% Pb and 243.0 g/t Ag (see Fireweed news release dated September 20th, 2018) in an interval containing the dense minerals galena-sphalerite-barite-pyrite-pyrrhotite. The two holes planned at Tom East will add definition to this high-grade zone and aim to facilitate a borehole muon survey to determine if a dense 3D body can be imaged around this step-out intersection to better target follow-up drilling (see Fireweed news release dated May 27th, 2021 for details of the borehole muon tomography survey).

One step-out hole is planned at Jason South to test the fault offset exploration target, outside of the current Jason South Inferred Mineral Resource of 8.93 Mt at 4.41% Zn, 5.28% Pb, and 68.0 g/t Ag (see Fireweed news releases dated January 10th, 2018, and reports filed on www.sedar.com for details). Within this Lower Jason South exploration target, historic drill hole JS82-086 intersected 13.8 m of 7.2% Zn, 5.3% Pb, 118 g/t Ag in addition to 9.2 m 1.6% Zn, 16.5% Pb, 92 g/t Ag and its wedge hole JS82-086W1 intersected 27.3 m of 8.0% Pb, 58 g/t Ag, 0.07% Zn. This planned hole is optimally placed to allow potential deployment of muon detectors to image the density of the exploration target to better guide follow-up drill holes.

A geological mapping program along with geophysical surveys will support the evaluation of regional targets within the context of the 2020 discovery of mineralization hosted in the same age rocks as those of the large Howards Pass deposit to the southeast. This new wave of zinc-lead-silver exploration in the district will examine a search space that has been previously overlooked and represents significant opportunities for additional discoveries.

Fireweed Zinc is a public mineral exploration company focused on zinc-lead-silver and managed by a veteran team of mining industry professionals. The Company is advancing its district-scale 940 km2 Macmillan Pass Project in Yukon, Canada, which is host to the 100% owned Tom and Jason zinc-lead-silver deposits with current Mineral Resources and a PEA economic study (see Fireweed news releases dated January 10, 2018, and May 23, 2018, respectively, and reports filed on www.sedar.com for details) as well as the Boundary Zone, Tom North Zone and End Zone which have significant zinc-lead-silver mineralization drilled but not yet classified as mineral resources. The project also includes large blocks of adjacent claims (MAC, MC, MP, Jerry, BR, NS, Oro, Sol, Ben, and Stump) which cover exploration targets in the district where previous and recent work identified zinc, lead and silver prospects, and geophysical and geochemical anomalies in prospective host geology.

zinc mining and processing: everything you need to know

zinc mining and processing: everything you need to know

Looking back on the history of mining and up to present-day techniques, many advancements have occurred in the way mined materials are extracted. Heavy-duty, durable and compact mining equipment has increased cost-effectiveness and the efficiency with which we mine. As a result, the mining industry has been able to reduce waste, as well as dangerous chemicals.

Compared to tin mining, the history of zinc mining is relatively short. In the 18th century, it was discovered that sphalerite, or zinc sulfide, could be smelted into brass, resulting in the first patented techniques. Since then, the zinc industry has progressed to the current zinc mining process and production methods used today.

From coatings to compounds, zinc is used in many areas of our lives. Whether its used in the home or an industry setting, zinc remains an important material. Under the below topics, there are many more specific ways in which zinc is part of our work and our lives.

Although the largest zinc mine is the Red Dog Mine, located in Alaska, zinc mines exist in 50 countries around the world. Among these 50+ countries, the worlds largest zinc producers are Canada, Australia, China, Peru and the United States. A few zinc mines in Canada, Australia, Ireland and Namibia will close within this decade due to depletion. The major types of zinc ore deposits are generally found to be sediment-hosted, volcanic-hosted, intrusion-related, Broken Ore type or Mississippi Valley Type.

The zinc mining process is conducted primarily underground, with more than 80 percent of all zinc extracted beneath the Earths surface. Eight percent of zinc is mined in open pits, with the remaining 12 percent being mined through both methods. Once its removed from the earth, the concentrate is roasted at a temperature of 950 degrees Celsius, causing zinc, sulfur and iron oxidization. After the zinc and iron oxides are reduced to powder form and leached with diluted sulfuric acid, the solution is neutralized and contaminants are removed via filtration. In the foundry, the zinc goes on to take its final form.

Zincs positive performance in recent years was largely the result of supply concerns caused by the closure of the Century and Lisheen mines. Supply worries have since abated somewhat in a March interview, Ryan Cochrane of CRU Group said there is a lot of supply coming.

He cited new mines coming online, including Gamsberg, owned by Vedanta Resources (LSE:VED), and the Century mine, now owned and restarted by New Century Resources (ASX:NCZ). Cochrane also pointed to returning idled capacity, includingGlencores (LSE:GLEN) Lady Loretta mine.

Given those factors, its interesting to look at where zinc mining takes place around the globe. Click to learn about the top zinc-mining countries, or read on for a brief overview of the worlds three largest zinc mines. From India to the US to Australia, key zinc-mining locations can be found around the world.

The Rampura Agucha mine in Rajasthan, India is the worlds largest zinc-mining operation. The open-cast/underground mine produced 5.7 million tonnes of ore during the 2017 fiscal year, including 619,981 tonnes of zinc in concentrate and 92,228 tonnes of lead in concentrate.

The mines proven and probable reserves currently sit at 46 million tonnes. Rampura Agucha was first commissioned in 1991, and is operated by Hindustan Zinc (BSE:500188), a subsidiary of Vedanta Resources. It is currently undergoing an expansion that will allow it to transition away from open-cast mining. Currently only about 52 percent of production comes from underground zinc mining.

Red Dog is a zinc-lead mine near Kotzebue, Alaska that was developed under a unique agreement between a US subsidiary of Canadas Teck Resources (TSX:TECK.B,NYSE:TECK) and NANA, which is owned by the Iupiat people of Northwest Alaska. The mine has a payroll of about $52 million, and provides 550 high-paying jobs in an area of the state where full-time work is difficult to secure.

In operation since 1989, Red Dog is now one of the worlds largest producers of zinc in concentrate, accounting for 5 percent of global zinc mine production and 79 percent of US zinc production. It is an open-pit, truck-and-loader operation. The original ore zone, called the Main deposit, was exhausted several years ago, and mining is now taking place at the Aqqaluk deposit.

Teck reported annual zinc in concentrate production of 542,000 tonnes for Red Dog in 2017. Across all its operations, the company estimates that in 2018 it will produce total zinc in concentrateof 663,000 tonnes, with refined zinc production hitting 307,000 tonnes.

Mount Isa Mines, a Glencore company, operates two separate mining and processing streams, copper and zinc. Its assets are located near Mount Isa in the Australian state of Queensland, and its zinc operations include the George Fisher underground mine and the Lady Loretta mine, where production has begun again after being suspended. The company also operates a zinc-lead concentrator and filter plant, plus a lead smelter and supporting services.

Glencores2017 annual report shows a production drop off of 22 percent from the previous year. The reduced output of 226,000 tonnes of zinc in concentrate was a conscious choice made by Glencore, which in 2015 started to battle falling commodities prices.
