In Australia, gold is the second largest industry for Vega, with the company serving around 150 mines for the precious metal. Within the gold industry, the company’s two biggest markets are level and pressure measurement.

Cyanide Use in Gold Mining Earthworks

Cyanide's efficiency makes mining more wasteful. Because cyanide leaching is very efficient, it allows profitable mining of much lower ore grades. Mining lower grade ore requires the extraction and processing of much more ore to get the same amount of gold. Partially due to cyanide, modern mines are. much larger than before cyanide was used;

Oct 01, 2020 Many electronic devices contain a small amount of gold, especially on the circuit board. This is because gold is a highly efficient conductor (better than copper) and it does not corrode, ensuring therefore that no interruption occurs in transmitting voltages and currents needed to run the device.

Elution and Carbon Reactivation Resource book

During the CIL process, gold is leached from the ore using an alkaline cyanide solution. The resulting gold cyanide complex ions are then concentrated and separated from the slurry by adsorbing onto activated carbon. Elution is the next step in the process, whereby the adsorption of the gold cyanide complex onto carbon is reversed.
