Embodiment 1

[0034] A copper-molybdenum separation flotation agent provided in this embodiment includes: 14kg sodium sulfide, 1300g sodium thioglycolate, 140g kerosene, and 2200g water glass.

[0035] This embodiment provides a kind of figure 1 The method for copper-molybdenum separation shown, wherein, with 1 representative sodium sulfide, 2 representative sodium thioglycolate, 3 representative kerosene, 4 representative water glass.

[0036] The method of copper molybdenum separation is as follows:

[0037] 1 ton of raw ore containing copper minerals and molybdenum minerals is thickened to obtain copper-molybdenum mixed concentrate. In this embodiment, the given copper grade in the raw ore is 24%, and the molybdenum grade is 0.45%. The pulp concentration of the raw ore is 25%, and the concentration of the copper-molybdenum mixed concentrate after thickening treatment is 40%.

[0038] Stir the copper-molybdenum mixed concentrate in the mixing tank, then add the copper-molybdenum flotat...

Embodiment 2

[0052] The main difference between the copper-molybdenum separation flotation agent provided in this example and the copper-molybdenum separation flotation agent provided in Example 1 is that the copper-molybdenum separation flotation agent provided in this example includes: 13kg sodium sulfide, 1300g mercapto Sodium acetate, 130g kerosene, 1900g water glass.

[0053] A kind of method for separating copper and molybdenum provided in this embodiment, the main difference with the method for separating copper and molybdenum that embodiment 1 provides is:

[0054] The copper grade in the raw ore provided in this embodiment is 21.36%, and the molybdenum grade is 0.395%. The pulp concentration of the copper-molybdenum mixed concentrate is 30%, and the concentration of the copper-molybdenum mixed concentrate after thickening treatment is 50%. The total amount of copper-molybdenum flotation agent used in the whole process of copper-molybdenum separation of copper minerals and molybde...

Embodiment 3

[0056] The main difference between the copper-molybdenum separation flotation agent provided in this example and the copper-molybdenum separation flotation agent provided in Example 1 is that the copper-molybdenum separation flotation agent provided in this example includes: 12kg sodium sulfide, 1250g mercapto Sodium acetate, 120g kerosene, 1700g water glass.

[0057] A kind of method for separating copper and molybdenum provided in this embodiment, the main difference with the method for separating copper and molybdenum that embodiment 1 provides is:

[0058] Copper-molybdenum mixed concentrate is produced by thickening raw ore containing copper ore and molybdenum ore. The given head grade is 18% copper and 0.35% molybdenum. The slurry concentration of the copper-molybdenum mixed concentrate is 28%, and the concentration of the copper-molybdenum mixed concentrate after thickening treatment is 45%. The total amount of copper-molybdenum flotation agent used in the whole proce...

Abstract

The invention provides a copper molybdenum separation flotation agent and a copper molybdenum separation method, and relates to the technical field of beneficiation. The copper molybdenum separation flotation agent comprises the following components in parts by weight: 10-15 parts of sodium sulfide, 1-1.5 parts of sodium thioglycollate, 0.1-0.15 part of kerosene, and 1.5-2.5 parts of water glass. The copper molybdenum separation flotation agent prepared through reasonable components and ratios thereof can exert the best separation effect to improve the problems of weak copper molybdenum separation effect and low molybdenum recovery rate. The copper molybdenum separation flotation agent realizes the copper molybdenum separation through flotation to reduce the energy consumption, and facilitates the copper molybdenum separation operation in energy shortage regions.

Description

technical field [0001] The invention relates to the technical field of mineral processing, and in particular to a copper-molybdenum separation flotation agent and a copper-molybdenum separation method. Background technique [0002] Molybdenum is an element that is rarely distributed in nature, and its average content in the earth's crust is about 0.001%. Globally, the United States has the most proven molybdenum resources, followed by Canada and Chile. my country is relatively rich in molybdenum resources, accounting for about 37% of the world's total molybdenum resources. Separation flotation technology has always been a major research topic in the field of mineral processing. [0003] At present, the copper-molybdenum separation flotation process mainly includes two schemes: copper-suppressed floating molybdenum and molybdenum-suppressed floating copper, among which the copper-suppressed floating molybdenum method is adopted by most mines. [0004] In recent years, miner...
