Analysis of iron content in the leaching process of nickel slag as raw material for manufacturing fero sulfate
Keywords:
ferrous sulfate, iron content, leaching, nickel slagAbstract
Slag waste is waste generated from the nickel processing and smelting industry. Each process of refining one tonne of nickel products produces 50 times solid waste, equivalent to 50 tons of this problem which causes the waste stockpile to increase. The analysis of the iron content in the nickel slag leaching process as a raw material for the manufacture of ferrous sulfate is quite interesting because nickel slag chemically still contains valuable minerals and metals, and the iron content in nickel slag is the most dominant. The purpose of this study was to determine the effectiveness of dissolving iron content in nickel slag from the leaching process which will later be used as a concentration for the manufacture of ferrous sulfate. This research is an experimental study to determine the dissolved Fe content that will be used to make ferrous sulfate coagulant products with concentrations of 0.2; 0.3; 0; 5 and 1 mol/L.
