The beneficiation process generates highvolume waste called ''tailings,'' the residue of an ore that remains after it has been milled and the desired metals have been extracted (, with cyanide (gold) or sulfuric acid (copper)). If a mining project involves the extraction of a few hundred million metric tons of mineral ore, then
Alluvial Gold Mining. Alluvial gold is found beneath the surface at the bottom of a creak or stream. Alluvial gold mining is the process of extracting gold from these creaks, rivers and streams and is generally considered to be the most environmentally friendly method of gold mining as a result of the reduced environmental impact when compared to underground mining.
After extraction, many types of raw minerals are then subject to processes such as crushing, milling, washing and chemical treatments. Wastewater is generated during mineral processing (, stone cutting, wash water, scrubber water), from equipment cooling, from mine dewatering, and from stormwater runoff at mines and processing plants.

These gold professionals are specifically in gold processing through various beneficiation technologies, for gold ore of different characteristics, such as flotation, cyanide leaching, gravity separation, etc., to achieve the processing plant of optimal and costefficient process designs.
Black sand deposits, which are composed of heavy metal materials such as iron and hematite, are common in areas where gold is found. While mining hobbyists typically regard the presence of black sand as an indicator of gold deposits, the sands themselves contain small particles of gold, called flour gold, and the sands are frequently processed for gold extraction.
Leaching dissolves the gold out of the ore using a chemical solvent. The most common solvent is cyanide, which must be combined with oxygen in a process known as carboninpulp. As the cyanide and oxygen react chemically, gold in the pulp dissolves. When workers introduce small carbon grains to the tank, the gold adheres to the carbon.
Gold is relatively scarce in the earth, but it occurs in many different kinds of rocks and in many different geological environments. Though scarce, gold is concentrated by geologic processes to form commercial deposits of two principal types: lode (primary) deposits and placer (secondary) deposits.
