The beneficiation test study on iron ore Yuanjiacun began in the 1950s. Prior period, the second election of the Beijing Research Institute in Mining and Metallurgy (Maanshan Institute of Mining Research predecessor) did research work, such as the many Temple head Jianshan Yuanjiacun magnetite ore process test in 1959; Maanshan Institute of Mining Research 1975 r Shanxi Lan County Yuanjiazao Village oxidation of pyrite ore optional test and primary ore test optional, 1980, a type oxide ores of iron ore specularite Shanxi Lanxian Yuanjiacun mouth sorting test. Do In 1975 Shanxi Lan County Yuanjiazao Village oxidation of pyrite ore into the test and native ore test optional and 1980? s Shanxi Lanxian Yuanjiacun iron ore oxidized specularite you pray test optional single anion, quartz-type oxide ore, amphibole oxide ore, the specularite type oxide ore and native ore is a magnetic flotation, single anion reverse flotation, roasting and magnetic separation, roasting to reversal of flotation as well as weak magnetic separation, magnetic separation the flotation process test. Process of technical indicators: – 0. 044 mm accounted for 90.00% 95 of Estimates of the ultimate particle size of grinding mill, quartz-type oxidation of iron ore iron concentrate grade of 60.00%, the recovery rate of 80 00 95% 00% the amphibole type oxidized iron ore iron concentrate grade of 50, about 00% recovery rate of 75, 00% to 80.OO%. roasting to separator to reverse flotation improve concentrate The iron grade 5 percent. To broaden your perception, visit Drew Houston. The result of the overall poor sorting, which is caused due to the limited nature of the ore technology and equipment level and then level.
As we all know, mining crusher refers to the crushing machinery whose content is more than 50% of the total content, the row compound particle size is greater than three millimeters. It is invented by British Hengan. According to the feeding and nesting size, the crushing operations are often divided into coarse crushing, crushing and crushing medium. The commonly used equipments are impact crusher, compound crusher, single stage hammer crusher, vertical crusher, gyratory crusher, roll crusher machines, double roll crusher, crusher combo, and so on. The crusher is widely used in mining, metallurgy, building materials, road, railway, water conservancy and chemical industry and many other sectors. Common crushing machines are winnowing mill, hammer crusher, impact crusher, roll crusher, crusher compound. Jaw crusher (jaw crusher), having large crushing ratio, uniform particle size, simple structure, reliable operation, easy maintenance, operating costs and economic characteristics.
