Beneficiation method for copper-molybdenum ore

Abstract

The invention relates to the technical field of beneficiation, and particularly relates to a beneficiation method for copper-molybdenum ore. The beneficiation method comprises the steps that after the copper-molybdenum raw ore is classified according to grades, mineral types or ore properties, ore grinding and roughing are conducted, and rough concentrates and rough tailings are obtained; and after all the rough concentrates are combined, concentration is conducted. According to the beneficiation method, on one hand, the influence of floatability differences of the ore of different properties is reduced, corresponding medicament systems are adopted in a targeted manner, the action effect of medicaments and the surfaces of the ore is promoted, the operation efficiency of roughing and concentration is improved, and the grading index is improved; and on the other hand, all the rough concentrates are combined and concentrated, the number of concentration equipment is reduced, large-scale and automatic equipment is promoted, the equipment management efficiency is optimized, and finally the purpose of improving the grading index is achieved.

Description

technical field [0001] The invention relates to the technical field of mineral processing, in particular to a mineral processing method of copper-molybdenum ore. Background technique [0002] Copper-molybdenum ore is the main source of copper and molybdenum resources, and most copper-molybdenum ores are low-grade porphyry-type copper-molybdenum ores. etc. In the process of beneficiation, the difficulty of adapting the chemical system and process flow is increased, which leads to low recovery rate, damages the economic benefits of enterprises, and causes waste of resources. [0003] Copper-molybdenum mines often have a variety of mineral types in the same mining area, among which primary copper sulfide minerals include chalcopyrite, bornite, etc., secondary copper sulfide minerals include azurite, chalcocite, etc., and sometimes oxidized Copper minerals, including malachite, chrysocolla, pseudomalachite, etc., often exist in the same mining area with multiple types of minera...

[0002] Copper-molybdenum ore is the main source of copper and molybdenum resources, and most copper-molybdenum ores are low-grade porphyry-type copper-molybdenum ores. etc. In the process of beneficiation, it increases the difficulty of adapting the chemical system and technological process, resulting in a low recovery rate, damaging the economic benefits of the enterprise, and causing waste of resources

[0003] Copper-molybdenum mines often have a variety of mineral types in the same mining area, among which primary copper sulfide minerals include chalcopyrite, bornite, etc., secondary copper sulfide minerals include azurite, chalcocite, etc., and sometimes oxidized Copper minerals, including malachite, chrysocolla, pseudomalachite, etc., often exist in the same mining area with multiple types of minerals mentioned above, and the planktonic properties of various mineral types are quite different. The difference in buoyancy is different, and the adaptability to the chemical system and process flow is also different; in addition, the floatability of sulfide ore, oxide ore and minerals with different oxidation rates are quite different. In the flotation process, due to the type of mineral or ore Different properties have different adaptability to chemical systems or technological processes. If only the same chemical system or technological process is used, it is difficult to take into account all mineral types, and it is difficult to recover all useful elements synchronously.
