Iron ore of a metamorphic deposition based Anshan iron deposit. Ores plant treatment is hematite quartzite, iron minerals are mainly artifacts hematite, hematite semi artifacts; gangue minerals are quartz, followed by a hornblende, chlorite. The ore has an obvious strip-like structure, and the particle size of the impregnation is fine. The particle size of the pseudo-hematite and quartz is generally 0.02~0.2mm. The ore needs to be ground to -200 mesh 80% to separate the monomer. The flotation is carried out by anion collector weak alkaline pulp flotation method, the adjusting agent is sodium carbonate, the dosage is 1.8kg/t, and the 20% aqueous solution is added. The second-stage grinding machine has a flotation pH of 8.5~9.5 and a slurry temperature of 30~33c. The collector is a mixture of oxidized paraffin soap 390g/t and tal oil 130g/t. The process flow is shown below. The obtained flotation index is When the ore grade is 33.00%Fe, the concentrate grade is 61.20, and the recovery rate is 77.95% Fe. Single toggle jaw crushers are designed to impart on a rock particle placed between a fixed and moving jaw plate. ... Both the jaw plates are bolted on to heavy block. The moving jaw plate is pivoted at the top end and connected to an eccentric shaft.
