and milling operations--solution mining (leaching). Basically gold and silver leaching involves spraying a cyanide so- lution on the ore to dissolve the metal values, collecting the solution contain- ing the dissolved metals, and recovering the metal from the solution. By elimi- nating milling, leaching reduces capital
Carbon-In-Leach. Carbon-in-leach combines leaching with the carbon-in-pulp process, creating a single unit process operation. Usually this method is chosen when native carbon (a high organics load) is present in the gold ore, adsorbing the leached gold and preventing its recovery.

Gold Extraction Process. Sod ium cyanide has been used in the extraction of gold from ore for over a century. Today it is still considered the most efficient extraction method with sodium cyanide used in the leaching process in most gold mining operations. Orica is one of the largest producers of sodium cyanide for the mining industry.
With the rising gold prices in recent years, it further stimulated the rapid development of gold mining industry. As the exhaustion of high-grade gold ore, researching on middle-low grade and refractory gold ore and strengthen the traditional gold recovery undoubtedly have become the main trend in global gold mining industry.

In 1998, approximately 70% of gold recovered from cyanide use was from vat-leaching operations, about 30% from heap-leaching operations.3 All in all, cyanide leaching is now used to process over 90% of gold ores (by weight) mined in the United States.4
Gold Mining with Cyanide REPORT ON I-147 Repeal of the Ban on Cyanide Heap Leaching in Gold Mining WHAT IS CYANIDE AND WHAT DOES IT DO IN THE ENVIRONMENT Cyanide is a general term, referring to various specific cyanide compounds. Cyanide (CN) itself is a simple, organic anion (negatively charged ion) consisting of carbon and nitrogen.
Cyanides 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

The micro-leaching tanks technology will run tests in three project locations Hulawa- Gorontalo, Obi-North Maluku, and Kulonprogo D.I Yogyakarta.
Most cyanide leaching is carried out at a alkaline pH of between 10 and 11, depending upon lab testing of individual ores and the optimum leaching/chemical use rates. The cyanide solution strength is also important in leaching gold, with the typical range of solution being in the 0.02% -0.05% NaCN. The gold particle size has a tremendous effect ...
