Embodiment Construction

[0021] The following examples are intended to further illustrate the present invention, but not to limit the present invention. The g / t mentioned in this application refers to the mass of the agent added per ton of raw ore. Said percentages are all mass percentages.

[0022] Copper-cobalt-nickel polymetallic deposits in a certain place in Australia are produced from sedimentary carbonaceous shale deposits. Due to long-term weathering, the mineral species and ore structure of the raw ore tend to be complicated. The ore hardness is 1~2, which can be depicted and stained with fingernails. The content of carbonaceous matter in the raw ore is as high as 4.41%; the content of clay minerals reaches 55.26%, which are mainly silicate minerals with layered structure such as hydrokaolinite and hydromuscovite, and the interlayers are combined by residual bonds, which can not only Adsorbs a large number of free metal ions, and also adsorbs many flotation reagents, which makes the flotati...

Abstract

The invention discloses a method for beneficiating high-peat copper sulphide ore and relates to a method for beneficiating nonferrous metals, which specifically relates to a method for beneficiating high-peat copper sulphide ore; regulating agent and composite inhibitor are added before floating ore pulp and after graining raw ore; flotation environment and mineral surface state in ore pulp are improved in the method disclosed by the invention; the inhibition capacity of inhibitor on easily-floated gangue mineral and selective collection of collecting agent on mineral are enhanced; compared with the traditional method for beneficiating pre-deslimed peat, a technical procedure is simplified by the invention; the loss of available mineral caused by pre-deslimed peat is avoided; and the recycle rate of copper is increased by about more than 18%.

Description

technical field [0001] The invention belongs to the field of mineral processing of nonferrous metals, and relates to a method for mineral processing of high-peat copper sulfide ore. Background technique [0002] The research on the influence of slime on flotation and how to eliminate the influence of slime on flotation has achieved rapid development in the last 20 to 30 years, and many new flotation processes and new flotation agents have emerged. If the flotation pulp contains more slime, it will bring a series of adverse effects on flotation. The main impacts are as follows: ①It is easy to be mixed in foam products, which will reduce the grade of concentrate; ②It is easy to cover the surface of coarse grains, affecting the flotation of coarse grains; ③Adsorption of a large amount of chemicals increases the consumption of chemicals; Sticky, the inflation condition deteriorates. The technological measures to solve this problem mainly include: ① use thinner pulp to reduce t...
