Embodiment 1

[0037] Please refer to figure 1 The embodiment of the present invention also provides a method for flotation of a copper-molybdenum mixed concentrate, which includes the following steps:

[0038] Step 101: Flotation of the raw ore containing copper and molybdenum to obtain a copper-molybdenum mixed concentrate;

[0039] In step 101, the flotation operation can be carried out in accordance with the conventional operation. During the flotation process, the raw ore containing copper and molybdenum is transported to a predetermined location through a belt and then the flotation operation is performed.

[0040] Step 102: After adding a copper inhibitor and a molybdenum collector to the copper-molybdenum mixed concentrate, roughing is performed to obtain a rough molybdenum concentrate and a slurry after separation and roughing;

[0041] Step 103: Sweep the slurry after the separation and coarse separation at least once to obtain a copper concentrate;

[0042] In this embodiment, the number o...

Embodiment 2

[0053] In this embodiment, the steps of the first embodiment are detailed and described in detail, which specifically includes the following steps:

[0054] A: Flotation of copper-molybdenum-containing raw ore is carried out to obtain a copper-molybdenum mixed concentrate; this step specifically includes the following operations:

[0055] 1. Grind the raw ore containing copper and molybdenum to obtain slurry;

[0056] Before the raw ore is subjected to primary selection, it needs to be ground (grinding to -200 mesh content 70.49%) in advance, the raw ore is ground into a slurry, and the obtained slurry enters the subsequent operation.

[0057] 2. After adding lime, butyl xanthate, and molybdenum collector to the slurry, a rough separation process is carried out to obtain a copper-molybdenum crude concentrate and a rough separation slurry;

[0058] In the rough separation process, butyl xanthate is used as a collector of copper and molybdenum, and No. 2 oil is used as a foaming agent, wh...

Abstract

The invention relates to the field of mineral product exploitation, in particular to a method for copper-molybdenum bulk concentrate floatation. The method for copper-molybdenum bulk concentrate floatation comprises the steps that raw ore containing copper and molybdenum is subjected to floatation, and copper-molybdenum bulk concentrate is obtained; copper inhibitors or molybdenum collectors are added into the copper-molybdenum bulk concentrate, then separation rougher flotation is carried out, and molybdenum rough concentrate and ore pulp after separation rougher flotation are obtained; the ore pulp after separation rougher flotation is subjected to at least one-time scavenging, and copper concentrate is obtained; and the molybdenum rough concentrate is reground to be in preset fineness, then concentration is carried out for 5-9 times, and molybdenum concentrate is obtained. According to the method for copper-molybdenum bulk concentrate floatation, the phenomenon of copper mine overgrinding is avoided, in addition, the good effect of copper-molybdenum separating is achieved, and energy loss during an operation process is lowered.

Description

Technical field [0001] The invention relates to the field of mineral mining, and specifically relates to a method for flotation of a copper-molybdenum mixed concentrate. Background technique [0002] At present, the main process of processing copper-molybdenum ore at home and abroad is the mixed flotation of copper-molybdenum minerals. The copper-molybdenum mixed concentrate is obtained through selection, and then molybdenum is separated from the copper-molybdenum mixed concentrate by flotation, and then the copper concentrate Molybdenum concentrate. The separation of copper and molybdenum mainly includes two methods: molybdenum floating copper and copper floating molybdenum. Because the operation is easy to achieve, most concentrators use copper and floating molybdenum methods to achieve copper and molybdenum separation. [0003] In the related art, when the copper-molybdenum mixed concentrate is processed, it is usually reground to reduce the particle size and increase the disso...
