Sulfide Ore Flotation Study to Achieve 85% Gold Recovery as DECREE from Minister and Mineral Resources Indonesia 1827 K/30/MEM/2018

Fulfilling the provisions of the Ministry of Agriculture as a company under IUPK (special mining business license) is a must for mining companies in Indonesia. In KepMen 1827 K/30/MEM/2018, it is stated that the gold commodity under special mining business license (IUPK) minimum recovery is 85% for gold. This study wants to find the solution of how 85% gold recovery will be achieved by conducting statistical analyses on laboratory test results to simulate operating strategy in regard to increasing flotation performance. The research will require models on kinetic flotation laboratory test results. The combination of variables between grind size, reagent (primary collector and secondary collector), and flotation retention time will result in a response recovery in the flotation circuit.
