  • Flotation of Copper oxide ore Fodamon

    The floatability of copper oxide ores is generally worse than that of copper sulfide ores, and is greatly influenced by the existing form of copper in minerals and gangue composition For example, when copper is in the form of carbonate (malachite, blue copper ore), the flotability is relatively good, while the flotability of silicate (silica malachite) is poor, free copper oxide is29/09/2021· Characteristics and floatability of main copper oxide ores Mineral names Chemical formula Copper content Specific gravity Hardness Color Flotability Malachite Cu 2 CO 3 (OH) 3: 575 5 354 emerald green Good flotability Azurite Cu 3 (CO 3) 2 (OH) 2: 555 38 354 dark blue The same as aboveA Brief Introduction to Copper Oxide Ores | Fote MachineryThe floatability of oxide copper minerals that are present in the ore containing carbonaceous and dolomitic gangue is significantly different from the flotation properties of oxide copper containing siliceous gangue minerals The presence of various types of clay slimes also has a significant effect on flotation properties of oxide copper minerals [2] 192 OXIDE COPPER19 Flotation of Oxide Copper and Copper Cobalt Ores
