There are two commercial methods available The first method utilizes arsenopyrite depression and pyrite flotation and consists of the following steps 1 Heat the bulk concentrate to 75 °C at a pH of 45 controlled by H 2 SO 4 in the presence of small quantitiesGet Price
Jan 01 2005 · Granulated matte is first leached with sulfuric acid in a countercurrent circuit for nickel extraction followed by copper removal via a series of autoclaves using high temperature and high oxygen pressure The finely divided leach residues are inputted to the PMR as final concentratesGet Price
The sulfuric acid leaching stage was studied based on a statistical approach applied to the experimental design Using the PlackettBurman method temperature of the leach solution stirring speed concentration of sulfuric acid and particle size of the ore were selected as the variables that had the largest effect on the experimental responseGet Price
Jul 01 2014 · In this work different flotation–preoxidation–cyanidation methods are considered for treating a lowgrade refractory gold ore On the one hand the results of selective flotation show that 22 and 311 of total Sb and As respectively remained in the final tailings and only about 28 of the total Au remained for further cyanidation processesGet Price
Jan 01 2016 · In addition sulfur dioxide is formed from the sulfide oxidation reaction and either converted to sulfuric acid in a traditional acid plant or converted to sulfate from its reaction with carbonate and hematite in the ore and with lime added to theGet Price
