Analysis Of The Percent Extraction Of Main Ridge Quarter 4 Ore By Bottle Roll Test Method At PT J Resources Bolaang Mongondow

Salman Abduhafizh, Yasmina Amalia

Abstract


One of the leaching methods used for oxide-type ores is heap leaching. The company that performs this method is J Resources Bolaang Mongondow. At J Resources Bolaang Mongondow there are several parameters for the heap leaching process carried out, such as ore size, NaCN and lime consumption, and basemetal content. This study aims to analyze the effect of grain size on the percent extraction and reagent consumption and analyze the effect of basemetal content on the percent extraction of gold through the bottle roll test method. The study used oxide gold ore of sizes +12, +6, and -6 mm. From the results of the experiments carried out, it was found that the highest extraction percent was produced in the -6 mm size of 97% which also had the highest lime and NaCN consumption of 5.89 kg/ton and 0.71 kg/ton. From these results, it is found that ore size greatly affects the percent extraction produced as well as the consumption of lime and NaCN used. In addition, the leaching process is influenced by the basemetal content contained in the ore.
