Embodiment 1

[0069] Embodiment 1 A copper-zinc ore ore beneficiation process.

[0070] There are many types of minerals in the ore of a copper-zinc mine, and the mineral composition is relatively complex. The ore mainly recovers valuable elements as copper and zinc, and a small amount of gold is associated with it. The copper minerals are mainly chalcopyrite, whose content is 4.25%, chalcocite bornite and copper blue content are less; the zinc minerals are sphalerite, whose content is 5.33%. The characteristic of this ore is that the chalcopyrite is distributed unevenly in coarse and fine grains, and the sphalerite is mainly distributed in fine grains. Gangue minerals mainly include quartz, feldspar, muscovite, sericite, tremolite, actinolite, biotite, carbonate minerals, chlorite, kaolin and so on. The gold and silver minerals in the ore mainly include gold and silver ore and silver-gold ore. The copper grade in the ore is 2.75%, the zinc grade is 3.26%, and the gold grade is 0.76g / t. ...

Embodiment 2

[0090] Embodiment 2 ore beneficiation process of a certain copper-zinc ore.

[0091] The mineral composition of a copper-zinc ore is relatively complex, and there are many types of minerals. The ore mainly recovers valuable elements as copper, zinc, and associated gold. Copper minerals are mainly chalcopyrite with a content of 4.03%, chalcocite, bornite and copper blue content are less; zinc minerals are sphalerite with a content of 5.85%. The characteristic of this ore is that the chalcopyrite is distributed unevenly in coarse and fine grains, and the sphalerite is mainly distributed in fine grains. Gangue minerals mainly include quartz, feldspar, sericite, tremolite, actinolite, carbonate minerals, chlorite, kaolin and so on. The gold and silver minerals in the ore mainly include gold and silver ore and silver-gold ore. The copper grade in the ore is 3.02%, the zinc grade is 4.55%, and the gold grade is 0.88g / t. The copper oxidation rate accounts for 2.86%, and the zinc ...

Abstract

The invention relates to the technical field of beneficiation, in particular to a beneficiation method for separating copper and zinc from copper-zinc sulfide ore. The invention discloses a beneficiation method for complex copper-zinc sulfide ore. The beneficiation process comprises the steps of an ore grinding method, a using method of a combined inhibitor in flotation and a using method of a combined collecting agent. The method, based on the principle of clean and environment-friendly production, aims to improve the recovery rate of copper, zinc and associated gold, reduce the problem of serious mutual content of copper and zinc concentrates and improve economic benefits. The beneficiation method is feasible in technology and copper-zinc minerals are separated in an environment-friendlymanner, wherein valuable metal complex copper-zinc sulphide ore is comprehensively recycled, use of sodium cyanide or an oxidizing agent in beneficiation can be omitted, the copper-zinc recycling rate is effectively increased, the precious metal gold recycling rate is increased, meanwhile, mutual content of concentrate impurities is reduced, economic benefits of enterprises are increased, and economic benefits of enterprises are increased. Meanwhile, environmental pollution caused by ore dressing tailing discharge is reduced, and industrial clean, environment-friendly and safe production is achieved.

Description

technical field [0001] The present invention relates to the technical field of ore dressing, and relates to a beneficiation method of complex copper-zinc sulfide ore, in particular to a beneficiation method for separating copper and zinc from copper-zinc sulfide ore, and in particular to the floating process of copper-zinc sulfide ore with complex coarse and fine grains embedded in it. Choose a separation method. Background technique [0002] Polymetallic copper sulfide zinc ore is one of the complex and refractory minerals in my country, and most of the zinc metal comes from sulfide ore resources. Zinc metal is widely used in galvanizing, battery manufacturing and other fields. In view of the insufficient domestic supply, my country needs to import a large amount of zinc every year Metals can meet the needs of economic development. There are many zinc sulfide ore resources in my country, usually associated with precious metals such as gold and silver, and rare metals such a...
