Abstract. The use of cyanide in order to extract gold and silver from ores on industrial scale has been successfully applied for 100 years. The ores after comminution are classified in certainFig. 1 shows the gold plant under investigation. The plant is divided into 4 main areas: (1) crushing, (2) grinding and sizing, (3) leaching, adsorption and filtration, and (4) elution and gold room. 2.1. Crushing The ore is stockpiled and the process begins by feeding the ore into a hopper with a loader. The ore is then drawnThe environmental impact of gold mines: pollution by

Levay & Schumann (2006) argued for the need for mines to haveThe SO 2 /Air process offers an effective means to treat gold mill effluents and to produce effluents containing concentrations of less than 0.5 mg/L for total cyanide and for each of the metals commonly found in gold mill effluents (e.g., copper, iron, nickel and zinc). The process can be applied to either aqueous reclaim water or directly toCyanide and removal options from effluents in gold mining

A Review of the Cyanidation Treatment of Copper-Gold Ores
Globally, copper, silver, and gold orebody grades have been dropping, and the mineralogy surrounding them has become more diversified and complex. The cyanidation process for gold production has remained dominant for over 130 years because of its selectivity and feasibility in the mining industry. For this reason, the industry has The SART (sulfidization, acidification, recycling, and thickening) process (SP) has been successfully implemented in gold cyanidation plants to address issues associated with high cyanide-soluble copper content ores. However, this process could produce a relatively low grade precipitate, decreasing the sale price when gold plants Two-Stage SART Process: A Feasible Alternative for Gold

Two-Stage SART Process: A Feasible Alternative for Gold Cyanidation
The SART (sulfidization, acidification, recycling, and thickening) process (SP) has been successfully implemented in gold cyanidation plants to address issues associated with high cyanide-soluble copper content ores. However, this process could produce a relatively low grade precipitate, decreasing the sale price when gold plants When a gold plant includes a flotation process, the copper precipitate produced by the SART process can be mixed with the whole copper concentrate. An example of this option is the Telfer SART plant, which sends the copper precipitate produced directly from thickener underflow into flotation plant (Barter et al., 2001; Simons and Designing the SART process A review ScienceDirect
