Embodiment 1

[0020] Include the following steps:

[0021] Step 1: One pre-rougher selection, three pre-sweeping, calculated according to the weight percentage concentration of the pulp: the pre-roughering operation pulp concentration is 15%; the first pre-sweeping operation pulp concentration is 12%; the second pre-sweeping operation The pulp concentration is 10%; the pulp concentration of the third pre-sweeping operation is 8%; the pre-roughing operation foam enters the first roughing operation, and the third pre-sweeping operation separates the tailings into copper concentrate 1. This step is aimed at low Grade, high muddy skarn copper and molybdenum ores, especially copper-molybdenum mixed concentrates with low molybdenum grade and high mudification characteristics, reduce the flotation concentration, reduce the floating of muddy minerals, and remove most of the muddy minerals and molybdenum in advance Other impurities effectively improve the stability of the subsequent copper-molybdenu...

Embodiment 2

[0026] Include the following steps:

[0027] Step 1: one pre-roughering, three times pre-sweeping, in terms of pulp weight percentage concentration: the pre-roughering operation pulp concentration is 17.5%; the first pre-sweeping operation pulp concentration is 12.5%; the second pre-sweeping operation The pulp concentration is 11.5%; the pulp concentration of the third pre-sweeping operation is 9%; the pre-roughering operation foam enters the first roughing operation, and the third pre-sweeping operation separates the tailings into copper concentrate 1;

[0028] Step 2: One roughing, three times sweeping, according to the pulp weight percentage concentration: the pulp concentration of the roughing operation is 9%; the pulp concentration of the first sweeping operation is 9%; the pulp concentration of the second sweeping operation is 9% The slurry concentration of the third sweeping operation is 9%; the tailings separated by the third sweeping operation are copper concentrate 2...

Embodiment 3

[0032] Include the following steps:

[0033] Step 1: One pre-roughing and three pre-sweeping, based on the weight percentage concentration of the pulp: the pre-roughing operation has a pulp concentration of 20%; the first pre-sweeping operation has a pulp concentration of 15%; the second pre-sweeping operation The pulp concentration is 13%; the pulp concentration of the third pre-sweeping operation is 10%; the pre-roughering operation foam enters the first roughing operation, and the third pre-sweeping operation separates the tailings into copper concentrate 1;

[0034] Step 2: One roughing, three times sweeping, according to the pulp weight percentage concentration: the pulp concentration of the roughing operation is 10%; the pulp concentration of the first sweeping operation is 10%; the pulp concentration of the second sweeping operation is 10% The slurry concentration of the third sweeping operation is 10%; the tailings separated by the third sweeping operation are copper c...

Abstract

The invention relates to an ultralow-concentration copper-molybdenum separating flotation method, and belongs to a copper-molybdenum separating flotation method. The pre rough flotation operation slurry concentration is 15-20%, the first-time pre scavenging operation slurry concentration is 12-15%, the second-time pre scavenging operation slurry concentration is 10-13%, the third-time pre scavenging operation slurry concentration is 8-10%, the rough flotation operation slurry concentration is 8-10%, the first-time scavenging operation slurry concentration is 8-10%, the second-time scavenging operation slurry concentration is 8-10%, the third-time scavenging operation slurry concentration is 8-10%, ten times of finish flotation is carried out, the first-time finish flotation operation slurry concentration is 8-10%, the finish flotation operation slurry concentration from the second time to the tenth time is gradually reduced, and the tenth-time finish flotation operation slurry concentration is 3-5%. The method has the advantages that the whole process operation is smooth, each operation flotation foam target mineral is clean, and copper-molybdenum separating molybdenum concentratequality is effectively ensured.

Description

technical field [0001] The invention relates to a copper-molybdenum separation flotation method, in particular to a copper-molybdenum separation flotation method for super-large low-grade, high-mud skarn type copper and molybdenum associated metal ores. Background technique [0002] In my country, molybdenum resources are extremely rich, accounting for about 37% of the world's total. At present, with the development of economic construction, the demand for copper and molybdenum is increasing. However, copper and molybdenum resources have many lean ores and few rich ores, serious co-association, many other useful components, fine particle size, and molybdenite and molybdenite. The similar buoyancy of copper sulfide ores makes it difficult to separate copper and molybdenum. Therefore, the research and application of copper-molybdenum separation technology is particularly important. At present, the copper-molybdenum separation flotation process at home and abroad is a roughin...
