Safeguards against silicosis in mining
Silica dust can be kicked up by all manner of drilling operations, but underground gold mining, which often involves drilling through rock with high quartz concentrations - sandstone and granite, for example - is a particular risk. As such, gold mines of South Africa, which are staffed by a mostly migrant workforce and often exceedingly deep, have become a global epicentre for mining-related silicosis.

Silicate mineral - Wikipedia
Silicate minerals are rock-forming minerals made up of silicate groups. They are the largest and most important class of minerals and make up approximately 90 percent of Earth's crust.. In mineralogy, silica (silicon dioxide) SiO 2 is usually considered a silicate mineral. Silica is found in nature as the mineral quartz, and its polymorphs.. On Earth, a wide variety of silicate minerals occur

What is Silica? | Eurosil
Since it is so abundant, quartz is present in nearly all mining operations. It is present in the host rock, in the ore being mined, as well as in the soil and surface materials above the bedrock, which are called the overburden. Most of the products sold for industrial use are termed silica sand. The word "sand" denotes a material whose grain size distribution falls within the range 0.06-2.00 millimetres. The silica in the

The Mining Process – Waihi Gold
A slurry of ground ore, water and a weak cyanide solution is fed into large steel leach tanks where the gold and silver are dissolved. Following this leaching process the slurry passes through six adsorption tanks containing carbon granules which adsorb the gold and silver. This process removes 93% of the gold and 70% of the silver.

Health Hazards of Mining and Quarrying - ILO
The most common processes that produce respirable silica dust in mining and quarrying are drilling, blasting and cutting silica-containing rock. Most holes drilled for blasting are done with an air powered percussion drill mounted on a tractor crawler. The hole is made with a combination of rotation, impact and thrust of the drill bit. As the hole deepens, steel drill rods are added to connect

Crystalline silica is found in concrete, masonry, sandstone, rock, paint, and other abrasives. The cutting, breaking, crushing, drilling, grinding, or abrasive blasting of these materials may produce fine silica dust. It can also be in soil, mortar, plaster, and shingles. The very small pieces of silica dust get in the air that you breathe and become trapped in your lungs. Even the very small
