The Concept and Characteristics of Copper, Lead and Zinc Oxide Ore
In the natural world, sulfide minerals are produced by the action of oxygen in air or water and ions in water. The oxidation process usually takes place in the upper part of the deposit. The thickness of the oxide layer can reach 10-15 m depending on the geological conditions. Ore by oxidation rate (percentages refer to a metal oxide minerals present state) different minerals can be divided oxide ores, and sulfide ore mixed mineral. Usually, the oxidation rate is above 30% for oxidized ore, and the oxidation rate is below 10% for sulfide ore. In between is a mixed ore.
Properties of Copper, Lead ore zinc oxide has the following characteristics: (1) the structure and configuration of the ore is complex, fine-grained disseminated, easily dissociate, and the nature of oxide minerals typically very brittle, easily finely ground clay of time; (2) The composition of minerals is very complicated. The same mineral deposits often contain a variety of oxidized minerals of the same metal, but their floatability varies greatly; (3) often contains a large amount of slime and soluble salts; (4) the difference of oxidized ore properties in different deposits Very big. Even in the same deposit, the degree of oxidation and the nature of the ore vary greatly in different sections. Therefore, flotation of oxidized ore is often difficult.
