Dublin, Feb. 06, 2020 (GLOBE NEWSWIRE) -- The "Stone Quarrying, Clay and Sandpits, and Mining of Phosphates in South Africa 2019" report has been added to ResearchAndMarkets.com's offering.This report on Stone Quarrying, Clay and Sandpits, and Mining of Phosphates, includes comprehensive information on the size and state of these sectors, production and trade data and corporate actions.There are profiles of 23 companies including Afrimat, which has 31 aggregate and sand quarries as well as limestone and silica mines, and other notable players in the sector such as PPC, Raubex, AfriSam and Lafarge Mining South Africa. Phosphate rock companies profiled include Foskor, which exploits the country's largest phosphate rock deposit and Kropz, whose Elandsfontein mine will exploit South Africa's largest sedimentary phosphate rock deposit. Stone Quarrying, Clay & Sandpits, and Mining of Phosphates Low activity levels in the construction sector and rising input costs are providing challenges for the quarrying and the phosphate rock mining sectors. The construction sector, on which the industry relies, continues to struggle, largely due to low government spending on infrastructure, while some industry operations have experienced community unrest.Infrastructure projects are increasingly being packaged into smaller parts to allow emerging construction companies to take part in infrastructure development, leading some quarrying and phosphate companies to adapt their business models. South Africa's quarrying sector consists of a large number of players, including global cement producers like LafargeHolcim, major South African companies like PPC, and many smaller producers.Phosphate Rock Developments The mining of phosphate rock is carried out by one large company, Foskor, and one smaller producer, Gecko Fert, while Kropz is developing a new mine. Foskor increased its production of phosphate rock concentrate but it continues to make losses and its board is reviewing its underperforming operations to develop a turnaround plan which may include it being modernised and possibly downscaled. Kropz, which has made a significant investment in the development of its Elandsfontein mine and processing facility on the West Coast, has delayed commissioning. Key Topics Covered 1. INTRODUCTION 2.

stone quarry cuts deep into elmhurst`s history - chicago tribune

Hammerschmidt came to Elmhurst from Naperville to help run the quarry. Elmhurst became a city in 1910, and Max became its second mayor, serving from 1911, when there were approximately 2,400 residents, to 1919, when the population had grown to 4,500.

The family name was changed to the less-Germanic Hammersmith in World War II by Max`s son George, company chairman until his death in 1983. Today, 61-year-old George Hammersmith Sr., Adolph`s great-grandson, is board chairman.

''I`m fourth generation and my son George Jr. is here,'' Hammersmith said in his oak-paneled office. ''My brother Charles is president and he has two sons here. Between the three of them, one probably will run the company.''

The company started making concrete blocks in 1920, and by 1929 produced mostly crushed-stone products. Concrete-block production stopped about 20 years ago, Hammersmith said, and emphasis now is on ready-mix concrete shipped to construction sites in the company`s 45 to 50 cement trucks. Trucks from other firms also pull into the Elmhurst yard from Ill. Hwy. 83 to fill up.

Quarrying, in which exposed stone is cut from the ground, stopped a few years ago when workers reached a 200-foot layer of shale at the bottom of the more than 200-foot-deep pit. They drilled through that to mine the limestone below.

The mine--at a constant 55 degrees--is lighted but miners wear lamps on their hardhats just in case. Heavy equipment such as horizontal drills are used to pry away the limestone, which goes on conveyer belts to an underground crusher.

Two trucks could drive side by side down a tunnel sloping 12 degrees from the bottom of the quarry down to the mine. When the limestone reaches the surface, it is crushed further and sent to an on-site plant to be mixed with cement and sand. From there it goes into the rotating barrels of cement trucks.

The limestone will run out in 60 to 75 years, Hammersmith said. Then the underground ''rooms'' left by the ''room and pillar'' mining operation are to be used as storage areas for anything from records to food to nuclear waste.

Explosive blasts from the underground mining have upset neighbors in west-central Elmhurst. After protests over noise and vibrations, company representatives met in November with neighbors and city officials. The six-day-a-week, twice-daily blasting schedule--once in the afternoon and once in the early evening--was cut in December to once a day, around 3 p.m.

City Manager Thomas Borchert, who said the city gets a few complaint calls each month, said the controversy involves several hundred homeowners and seems to be settled. The city went to the state Department of Mines and Minerals and the federal Mine Safety and Health Administration for guidance.

''That`s not to say there weren`t concerns. They said they didn`t take issue that the noise and vibrations could be problems for the neighbors, but the operation was within safe and tolerable limits,'' Borchert said.

''I did go to a home where the owners expressed concern. You could hear the (blasting) noise and feel the ground shake. There`s always going to be a need for the quarry ownership and the neighbors to work and live together. I think they did that in changing the blasting schedule.

The quarry has a good safety record, Chairman Hammersmith said. ''No one has been killed since I`ve been here--and that`s 37 years.'' Hammersmith lived on Church Street in Elmhurst until 1960 when his family outgrew the house. The family now lives in an unincorporated area south of Glen Ellyn.

Jean Baker of the Elmhurst Chamber of Commerce said residents fill at least 75 percent of the 50 jobs at the stone company. The firm has 175 employees in its eight plants. Others are in Warrenville, Barbers Corner, Plainfield, Bartlett, Kaneville, South Elgin and Sleepy Hollow.
