Jan 21, 2020 South Africas reef deposits, especially gold and platinum-bearing ore bodies, are narrow and tabular. While legislation dictates a minimum operation height of 800 mm in areas where people work, some of the countrys narrow reef mines have ore bodies with thicknesses of less than 500 mm, which results in ore dilution, as waste ore with zero economic value is also mined.
Synthetic gypsum is a by-product of various industrial processes, most notably the generation of electrical energy through the burning of coal when using wet-lime scrubbers to control emissions. The overall market by 2029 is forecast to grow to 320 million tonnes, and an approximate value of $1.7 billion. Download Brochure.

small-scale mining with mines only a few metres deep, through large-scale alluvial mining and the most infamous gold panning. The area therefore is affected by the environmental impacts of each of these mining methods. It is a fact that whichever mining method, gold mining has environmental impacts that one needs to be always aware of.
There are four main mining methods underground, open surface (pit), placer, and in-situ mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments.
