WebMar 13, 2024 · The selective separation of chalcopyrite from galena (lead sulfide) through the flotation method is still a challenging task in the field of mineral engineering. Mercaptoacetic acid, though a common depressant of many gangue (commercially worthless) minerals, has shown to be less selective in the flotation separation of … WebGalena often occurs with perfect cubic cleavage. If you were to make a cube of pure galena measuring exactly 1.0 cm on a side and place that cube on a laboratory balance, you would find that its mass is 7.58 g—its density is 7.58 g/cm3, and its specific gravity is: 37.58 g/cm3 ÷ 1.0 g/cm = 7.58 Densities of minerals
