CONSEP ACACIA: THE FINEST IN LEACHING TECHNOLOGY

Further, LeachAid allows anaerobic dissolution of gold, and thus allows the Consep Acacia to use heated leaching for even faster kinetics and more complete leaching. In 2011, an independent study conducted in Perth, Australia compared the Consep Acacia to a rival product, operating in a gravity gold circuit. The Acacia replaced the competitor machine, and in addition to drastically increasing ...

Gravity Leaching With the ConSep ACACIA Reactor — Results ...

By removing the slow leaching species the cyanide concentration in the circuit can be lowered without producing a soluble tail. The result is a reduction in the overall cyanide consumption. In considering these points the plant’s operation will be examined in three different time frames: • Pre ConSep ACACIA Reactor - October 1998 to January 1999 (inclusive). This four-month period was ...

Cyanide Leaching Chemistry Gold Cyanidation

The reactions that take place during the dissolution of gold in cyanide solutions under normal conditions have been fairly definitely established. Most agree that the overall cyanide equation for leaching and cyanidation of gold is as follows: 4 Au + 8 NaCN + O2 + 2 H20 = 4 NaAu(CN)2 + 4 NaOH

The Metallurgy of Cyanide Gold Leaching – An Introduction ...

20/10/2014  Leaching gold with a cyanide solution remains the most widely used hydrometallurgical process for the extraction of gold from ores and concentrates. Despite the difficulties and hazards of working with cyanide, no other process has yet been proven to be an economic viable alternative. A paper published by L. Elsner in 1846 first correctly identified the chemical reaction that forms the basis ...

Inside the drum, the ore concentrates mix with a typically strong 1-2% cyanide solution and pure oxygen (in the case of gold extraction), known as intensive leaching. Specialised baffles inside the drum keep solids in constant contact with the chemical solution. The correct combination of chemicals and ore, plus the slow rolling action of the drum, creates a highly efficient leaching reaction.
