Embodiment 1

[0025] This method is used for the treatment of ore in Diqing, Yunnan Province. Diqing ore contains a large amount of pyrite and pyrrhotite, accounting for 22% of the total ore. The raw ore contains 13.06% of sulfur and 25.97% of iron, and The ore, pyrrhotite and pyrite have a close symbiotic relationship, and some ores are often wrapped with each other. The flotation agent used is butyl sodium xanthate (granular) produced by Shandong Qixia Tongda Mineral Processing Chemical Co., Ltd.; figure 1 Shown:

[0026] A method for flotation treatment of high-sulfur iron-copper ore, including roughing of raw ore, beneficiation and sweeping of tailings, specifically through the following steps:

[0027] 1) The raw ore is prepared into a pulp with a mass concentration of 29%. When entering roughing, add 40g per ton of raw ore, and add a flotation agent with a mass concentration of 5% in the pulp for roughing. The foam after roughing is sent to into the concentration I, and control the m...

Abstract

The invention relates to a high-pyrite copper ore flotation treatment method. The high-pyrite copper ore flotation treatment method is characterized by comprising the following steps: 1) after raw ores are roughly separated, foams are fed for finish separation; and rough-separated tailings are separated for scavenging I and scavenging III; 2) foams after finish separation I are fed for finish separation II; and tailings in finish separation I are fed for finish scavenging; 3) foams after finish separation II are fed for finish separation III to obtain copper concentrates; and tailings in finish separation II are fed for finish scavenging; 4) foams after finish scavenging are returned for finish separation I; tailings in finish scavenging are separated to feed for scavenging I and scavenging III; 5) tailings in scavenging I are fed for scavenging II; foams are fed for magnetic separation; foams in scavenging II are returned for scavenging I; and tailings in scavenging II are fed to a tailing warehouse; 6) tailings in scavenging III are fed for scavenging IV; foams are fed for magnetic separation; foams in scavenging IV are returned for scavenging III; and tailings in scavenging IV are fed to the tailing warehouse; and 7) nonmagnetic matters after magnetic separation are returned for rough separation; and magnetic matters are fed to the tailing warehouse. The copper concentratesare high in recovery rate and grade; the problem of influence on the flotation separation effect by great increment of the load due to total introduction of high-pyrite contained middlings in scavenging I is solved; the process is simplified; and the cost is reduced.

Description

technical field [0001] The invention relates to a copper ore flotation treatment method, in particular to a high-sulfur iron-copper ore flotation treatment method, belonging to the field of copper ore flotation. Background technique [0002] In terms of flotation research and development of high-sulfur iron-copper ores, there are few studies on the influence of harmful components on the separation efficiency. However, these methods have corresponding disadvantages in different degrees in the actual production process. The high pH value forcible suppression method is to forcibly suppress by adding a large amount of lime to increase the pH value, which will lead to continuous production. The entrainment loss of living organisms is serious. The middle ore is treated separately and the tailing method is to separate the middle ore by flotation to form an independent flotation system. However, the separation efficiency of the middle ore flotation part is extremely low, and the con...
