Keysource said the mining area is "one of the last remaining high-grade silica deposits in South Africa" and not opening the mine would have an impact on jobs. In its papers, the company says its Athlone mine, which provides all the sand for its Bellville glass plant, is reaching the end of its life, and reserves will be depleted by 2025.
Impacts of Silica Mining Missouri Coalition for the Environment EFFECTIVE CITIZEN ACTION SINCE 1969 Silica sand, also known as fracking sand, quartz sand, white sand, or industrial sand, is made up of two main elements: silica and oxygen. Specifically, silica sand is made up of silicon dioxide (Si02). (Shaw Resources)

Sand miners in the country overlook the fact that river sand mining has damaging knock-on effects on other sectors of the economy, on the livelihoods of people living with the rivers, and on biodiversity and environmental sustainability in general.
Most serious exposure to silica is linked to construction, and workers in the manufacturing, mining, and transportation and warehousing industries may also have some exposure to silica. Primary exposure to silica is inhalation. Ingestion and skin absorption are not significant and it's the effect of silica on lungs that leads to silicosis.

Silica exposure is a well-known danger for workers in mining and construction. With the spread of frac sand mining, however, silica air pollution has also become a danger for residents near sand mining and processing operations. Children, older adults and people with respiratory diseases are especially at risk.
One common type of crystalline silica is quartz. Silica can be found or manufactured in different forms, broadly divided into crystalline and non-crystalline (amorphous). This information focuses on respirable crystalline silica, which is the more hazardous form. Silica is a major constituent of many types of sand.

Sand is an indispensable natural resource for any society. Despite society's increasing dependence on sand, there are major challenges that this industry needs to deal with: limited sand resources, illegal mining, and environmental impact of sand mining. The purpose of this paper is twofold: to present an overview of the sand market, highlighting …
The specifications for each use vary, but silica resources for most uses are abundant. In almost all cases, silica mining uses open pit or dredging mining methods with standard mining equipment. Except for temporarily disturbing the immediate area while mining operations are active, sand and gravel mining usually has limited environmental impact.
