Abstract
Effect of bacterial solution on materials with various silica content: quartziferous, gold-bearing, oxide-nickel, copper-molybdenum ores and copper-nickel sulfide concentrate, has been studied. Copper-molybdenum sulfide ore grinding studies have been performed; density and porosity, as well as magnetic fraction content variations in these materials have been analyzed following their pre-treatment with bacterial solution.
keywords Ore, bacterial oxidation, bacterial solution, grinding, density, porosity, magnetic fraction.
