kamoa-kakula copper mine dewatering tailings for backfill with flsmidth vacuum disc filters - international mining

FLSmidth vacuum disc filters are playing a vital role in preparing tailings slurry for a backfill application at the new Kamoa-Kakula copper mine in the Democratic Republic of Congo (DRC). The Kamoa-Kakula Copper Project is a joint venture between Ivanhoe Mines (39.6%), Zijin Mining Group (39.6%), Crystal River Global Limited (0.8%) and the Government of the Democratic Republic of Congo (20%).

According to Maria-Paula Lucero, Sales and Account manager at FLSmidth, the company supplied four 3.8 m diameter disc filters, each comprising 14 vacuum discs. They are installed in two modules, with two units in each. This provides a cost effective dewatering strategy resulting in a cake dry enough to be mixed with cement and other additives before being conveyed underground to be placed in mined-out workings as backfill.

The efficacy of the vacuum filter in this application allows the mine to consistently achieve its targeted level of dewatering, says Howard Areington, General Manager Projects and Account Sales at FLSmidth. This, in turn, means that the amount of cement and additives can be optimised, keeping operating costs down. Areington highlights that vacuum disc filters are the preferred technology for tailings dewatering in backfill applications, being the most cost effective form of vacuum filtration per square metre of footprint.

A range of ancillary equipment was provided as part of the scope of supply, according to Lucero. This included the liquid-ring vacuum pump with capacity to pump almost 15,700 m3/h at a pressure of 67 kPa, as well as filtrate receiver and a filtrate pump of 32 m3/h capacity. FLSmidth also supplied a 1,060 gallon snap air receiver, a 750 kPa air compressor, a plant air receiver and an air drier. The water used in the filter vacuum pump needs to be potable so it was important for the design to recycle as much as possible. It is therefore recirculated through a closed circuit, with a cooling tower added to dispel heat from the water before it is re-introduced to the system.

With disc filters delivering a drier product with more water savings, FLSmidth has provided this technology to many projects around the world, says Areington. With FLSmidths global reputation in the field for vacuum filtration backfill applications, we have secured a significant portion of this market also supplying some of the largest vacuum disc filters in use today.

A considerable portion of the disc filter installation was locally manufactured in South Africa, he notes. It was shipped in components to site, and installed by a third-party engineering company under FLSmidth supervision. Despite the challenges presented by the COVID-19 pandemic, the units were manufactured and delivered within a timeframe in line with the customers expectations.

Our heavy-duty vacuum systems can be custom-built to meet the exact requirements of clients to handle the toughest mining environments in the gold, platinum, nickel, copper and other similar industries. These vacuum systems are proven to be highly efficient in the recovery of high-grade material that is generally very fine and cannot be collected and transported with conventional equipment. Industrial and central vacuum equipment for mining We make vacuum units for material spillage removal and recovery in industrial processing plants. These systems handle materials such as gold, alumina, cement, platinum, ferrochrome, iron ore and others, and are very effective at cleaning spillage material around and especially under conveyor belts and in areas around the processing plants where conventional equipment cannot be used and manual labour is the only alternative. Central vacuum systems allow for a more fixed and customised solution to be offered and have the benefit of being easy-to-use. They become an integral, and sometimes invaluable, part of the plant or mine in the area that they are installed. Vacuum trucks for cleaning contractors Vacuum trucks allow complete independence and greater flexibility due to the complete mobility that they offer. They are ideal for the cleaning contractor or plant that needs a mobile vacuum to cover several areas. These systems can either be truck-mounted or combination-towed systems where the collector tank is built onto the truck and the trailer-mounted vacuum unit is towed behind the truck. Conveyor belt return side vacuum cleaners Conveyor belt return side vacuum cleaners are stationary. They are permanent installations that have a custom-built nozzle unit that attaches to the bottom of a conveyor belt and in most cases is able to remove between 85% and 95% of the material that stays on the return side of the belt before it can cause more spillages. Vacuums and accessories for mining applications We also offer smaller vacuums for light plant cleaning, as well as dedicated belt cleaning systems and robotic mechanised hose control for access to hazardous and confined areas. A wide range of accessories are also available. Custom-built vacuum systems for the mining industry We have the experience and know-how to design and manufacture custom systems to meet the stringent requirements of our clients. Standard vacuum machines are available in an electric range with power output of 15kw right up to 110kw, as well as diesel with power outputs of 37kw up to 230kw.

ceo vacuum at anglogold turns it into worlds worst mining stock

ceo vacuum at anglogold turns it into worlds worst mining stock

AngloGold Ashanti has had a bad year, with the companys lack of a permanent chief executive officer and a suspension of its Ghana mine operations weighing on the stock. But with shares now cheap compared with peers, analysts see potential for upside.

Shares of the worlds third-largest gold producer have dropped 30% in the past year, making it the worst-performing stock in the 113-company Bloomberg World Mining Index. It also trails peers on South Africas FTSE/JSE Precious Metals and Mining Index, which has gained 20% in the same period.

Investor sentiment began to sour three days after the companys shares rose to a record on July 27. Thats when AngloGolds CEOKelvin Dushniskyshocked stakeholders by announcing his resignation. The stock on Tuesday fell to the lowest since March 2020, and trades at a forward price-to-earnings ratio of 8.5 times compared with 10.8 for the Bloomberg mining index.

AngloGold is a good turnaround stock at this point, being one of the cheapest large cap gold stocks globally, said Bloomberg Intelligence mining analyst Grant Sporre. Appointing a CEO and resuming mining operations in Ghana,would all be positive catalysts and may be enough for the stock to play catch up to peers, even if gold prices were to flatline.

The companys move to boost its dividend fivefold earlier this year hasnt helped the shares. The key trigger for investors will be the appointment of a permanent head, according toRaj Ray, director of metals & mining research at BMO Capital Markets. Interim CEO Christine Ramon has been running the company since Dushnisky quit last year.

The search for a permanent CEO is a top priority for the board, which is fully-focused on securing the best candidate for the role,Chris Nthite, a AngloGold spokesperson, said in an email on Tuesday.

While AngloGold is yet to decide on its CEO, rival Gold Fields has had a smooth transition. It named former Anglo American Platinum bossChris Griffithas head, to succeedNick Holland.Gold Fields shares have gained 13% in the past year.

Many analysts remain sanguine. AngloGolds recommendation consensus a gauge of analyst confidence in a stock on a scale of 1 to 5 stands at 3.7, up from 3 in August last year. Nine analysts forecast the companys shares will rise an average 27% in the next 12 months, according to data compiled by Bloomberg.

AngloGolds share price is poised to rise even if gold prices fall, said Rene Hochreiter, an analyst at Johannesburg-based Noah Capital Markets. Thats because the company is making quite a nice profit, so the target price should be about 30% higher, he said.

Still, investors will be assessing the companys ability to get its key Obuasi mine in Ghana back on track, after the operations were suspended last month following the death of a miner in a fall-of-ground incident.

While the suspension will curb AngloGolds 2021 output, the company is doing an assessment of the mine design, mine schedule and ground management plans, before resuming production in a phased manner, Nthite said, without giving a timeline.

The company also has other challenges. Its battling to repatriate more than $461 million of its profit from the Democratic Republic of Congo, and resolve challenges with value added tax with the government in Tanzania.
