Pyrite cinder production of other products

<

Jiang Lirong introduced sulfuric acid was dissolved burning pyrite metal oxide in the slag, reduction with iron shavings Cu, and concentrated in vacuo to precipitate Fe 2 (SO 4) 3, used to make efficient static agent - ferric sulfate, the residue Gold is recovered by cyanidation, which can increase the grade of Au by 5 to 8 times. According to preliminary analysis, each ton of slag can create an economic benefit of about 240 yuan, which creates a new prospect for the comprehensive utilization of pyrite slag.

Iron-based magnetic powder is an extremely important magnetic recording material and belongs to high-tech products. The iron-based magnetic powder mainly has Fe 3 O 4 , γ-Fe 2 O 3 and a-Fe magnetic powder. China's magnetic tapes use γ-Fe 2 O 3 magnetic powder mainly for import. Therefore, it is of great significance to strengthen the research of the above-mentioned products and strive to achieve localized and industrialized production as soon as possible. The general preparation process of iron oxide magnetic powder is:

The preparation process of metal ferromagnetic powder is:

After pyrite cinder with a binder (CaO) were mixed by shaking summarized molding, activation, drying, SW type is made efficient desulfurization agent, H biogas, gas, coal gas, etc. 2 S removal. The saturated sulfur capacity is 9.5%, which is regenerated by air oxidation. When the accumulated sulfur capacity of the desulfurizer is 20%, it can be used to produce sulfuric acid. SW desulfurizer has high purification degree, and has good desulfurization effect on biogas generated by water gas, wine plant sewage treatment and H 2 S in coke oven gas, and can reduce H 2 S content from 3000 to 5000 mg/m 3 to 20 mg/ Below m 3 , meet national emission standards. The operation is simple, the use of regeneration is convenient, and has good environmental and economic benefits.
