Gold Mine Tailings: A Potential Source of Silica Sand

Most gold mine tailings are composed mainly of industrial sand (i.e., silica) and silica sand is best described as a granular material that is composed of majorly quartz and trace amounts of coal, clay and other minerals . In some instances, it is referred to as either quartz or industrial sand and is widely applied in many engineering applications.

Rebellious Gold Extraction from Gravity Concentrates

2018-4-16  When gold occurs in mining waste for a long time, it becomes coated with dense films of hydroxide of iron, manganese, copper and silver sulfides, hydromica powder and clayey particles, which greatly complicate concentration of such gold by gravity. An efficient method to remove such coatings from gold is treatment of waste using chemical reagents based on halogen-containing compounds.

Gold E Traction From Sand Tailings - METTA-RAUM

2021-4-28  Tailings are a by-product of a gold mining process that was common in the late 1800s and early 1900s. Rocks that contained both gold and arsenic were crushed and then spread over liquid mercury to remove the gold. The mercury was then evaporated, leaving the gold. The remaining sand-like substance is known as tailings. They include arsenic and ...

Paper: Characterization of Cyanide in Gold Mine

Abstract: Numerous old gold sand and slimes tailings dumps on the Witwatersrand have been reprocessed since the 1980s for residual gold extraction using cyanide as a lixiviant. There are numerous technologies available by which many cyanide species may be decomposed. However, at most gold mines in South Africa, cyanide is simply discharged with the effluent and tailings
