Problems solved by technology

Copper concentrates are obtained through the conventional three-time roughing and one-time sweeping method. The screening efficiency is low, and there are still a large amount of copper ore in the tailings, which is not conducive to the effective use of energy.

Embodiment 1

[0022] Such as figure 1 As shown, Fig. 1 is a process flow chart of the method for converter slag copper magnetic levitation combined beneficiation shown in Example 1.

[0023] A method for combined converter slag-copper magnetic-flotation beneficiation, comprising the following steps: raw ore undergoes ore grinding, regrinding, two classifications, two roughings, two sweepings, two magnetic separations and one beneficiation to obtain copper concentrate And copper tailings, copper concentrate is filtered to obtain final copper concentrate, and copper tailings are filtered to obtain slag tailings.

[0024] Further, the two magnetic separations include one-stage magnetic separation and two-stage magnetic separation; preferably, one-stage magnetic separation means that a stage of graded grit enters the magnetic separator for magnetic separation, and the bottom product of the first-stage magnetic separation enters the second-stage magnetic separation. The separator performs two-s...

Abstract

The invention discloses a converter slag copper magnetic levitation beneficiation combined method. The converter slag copper magnetic levitation beneficiation combined method includes the following steps: ore grinding, regrinding, two times of grading, two times of roughing, two times of scavenging, two times of magnetic separation and a time of concentration are carried out on raw ore, and copper concentrates and copper tailings are obtained; the copper concentrates are filtered to obtain a final copper concentrate product, and the copper tailings are filtered to obtain a slat tailing product. According to the method, the step of two times of magnetic separation is additionally set, after magnetic separation is carried out, elementary substance copper most of which can not be grinded to be fine is firstly produced, the ore grinding classifying burden is reduced, the grinding and levitation working procedure capacity is improved, the production cost is reduced, and the slag ore dressing recovery percentage is improved.

Description

technical field [0001] The invention belongs to the technical field of comprehensive utilization of slag, and in particular relates to a method for combined beneficiation of converter slag with copper and magnetic floating. Background technique [0002] Usually converter and blowing furnace slag contain high copper content, some domestic copper smelters use it as return material to copper blast furnace to recover copper, and the final discarded slag is only copper water quenching slag. Although converter and blowing furnace slag contain high copper content, as smelting raw materials, its copper grade is lower than that of copper concentrate, which not only increases smelting energy consumption, affects smelting production efficiency, but also has a low level of comprehensive utilization of resources. [0003] There are two methods commonly used in my country to deal with copper slag: one is the fire method, that is, the dilution furnace is used for dilution. Due to return...
