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, ...

Embodiment Construction

[0030] Such as figure 1 and 2 As shown, the mineral processing system of the present invention at least includes a sulfide ore concentration pool 1, a ball mill 2, a spiral classifier 3, a mixing tank 4, a roughing flotation machine 5, a sweeping flotation machine 6, a selection flotation machine 7, a coarse Separation shaking table 8, sweeping shaking table 9, sulfur concentrate pool 10, tin concentrate pool 11, and tailings pool 12.

[0031] In one embodiment of the present invention, the desulfurization flotation production rate of high sulfide ore is 150-250 tons / day sulfide ore, the output tin content is 0.60-1.2%, and the sulfur content is 10-20%. The concentration is 9%-20%.

[0032]The sulfide ore with a concentration of 9%-20% is discharged into the concentration pool 1 to concentrate the pulp to a concentration suitable for ball mill grinding, and the concentrated overflow water is collected separately to enter the production process water. The ore pulp is precipi...
