Mineral processing technology of recycling tin metal from high sulphide ore

Abstract

The invention relates to a mineral processing technology for recycling tin metal from high sulphide ore. The mineral processing technology for recycling the tin metal from the high sulphide ore is characterized in that desulfuration floatation is firstly conducted on tinstone polymetallic sulphide ore, tin valuable mineral is recycled from the sulphide ore, and sulphide ore collector agents and foaming agents are applied to floatation. Preferably, ferric sulfide in the sulphide ore are separated and floated through floatation, enrichment of valuable mineral entering reselection is improved, and separation is conducted on valuable tin-containing mineral. Preferably, floatation equipment comprises a roughing floatation machine, a scavenging floatation machine and a concentration floatation machine; reselection equipment comprises a roughing shaking table and a scavenging shaking table. Preferably, a settling pond or a concentration pond is arranged at the front end of a mill. Preferably, sulphide ore pulp with the concentration ranging from nine percent to twenty percent is sedimented and concentrated to the sulphide ore with the concentration ranging from sixty percent to eighty percent through the concentration pond. Preferably, the sulphide ore collector agents are butyal xanthate, and the foaming agents is 2# oil. The mineral processing technology for recycling the tin metal from the high sulphide ore can improve the recycle utilization rate of the tin metal, and the environmental friendliness is high.

Description

technical field [0001] The invention relates to a beneficiation process for recovering tin metal from high sulfide ore, which is desulfurization flotation in the beneficiation process of refractory cassiterite polymetallic sulfide ore, and recovers tin valuable minerals from sulfide ore, which belongs to mineral processing engineering technology field. The invention utilizes the ore dressing principle of combining flotation and gravity separation to realize the recovery of tin metal, so as to improve economic benefits and resource recovery utilization rate. Background technique [0002] For refractory cassiterite polymetallic sulfide ore, in the desulfurization flotation process of ore dressing, cassiterite and sulfide ore are associated in the grinding process, so the minerals are often not completely dissociated; in addition, the amount of flotation reagents and mineral properties The change does not adapt, and there is a difference in the amount of addition. Therefore, ...

AI Technical Summary

Problems solved by technology

Therefore, in the process of desulfurization flotation, it is inevitable that the useful mineral cassiterite will be floated together and discharged into the tailings pond for discarding, resulting in the loss and waste of valuable metals such as tin

[0003] In the prior art, some enterprises adopt the flotation process, and some enterprises adopt the gravity beneficiation process, but it is difficult to recover the valuable metals in the high sulfide ore

There is a technical bias in the existing technology, that is, only one of them is selected in the flotation and re-election processes, and no one has ever considered using both, let alone how to connect flotation and re-election equipment Realize and use
