巩义鑫 China Machinery Mining knowledge editing: iron ore mining technology requirements: My little rich iron ore, industrial grade set at greater than 45%, the lower the phosphorus, and lower the cost of smelting iron ore sorting, is favored smelter, the higher the price. Two types of mining equipment: 1. open-pit mining: low cost, high-profit, is mainly used to dig the rise, loaders coal mine slag machine, automobile, air drills, explosives. 2. underground mining: high cost, but also supports and tunnel ventilation, mine laying track Cinder machine, using specialized equipment train transport to the surface. As for the problem of rational use of resources, mine exploitation unit is generally difficult to achieve, will pollute the environment and damage during mining, and slag is basically useless, if it is to use lead-zinc smelter slag machine will other elements in the ore is separated, bauxite used for other purposes: mainly in the road in the town of trickle Xiping, ore boehmite, gibbsite, due to the presence of oxygen of fit, twenty years trioxide aluminum (AL2O3). 30- lead-zinc ore grade for non-ferrous metals. On the territory of the lead and zinc, the wider distribution mines have identified 11: ⑴ crescents Hill lead-zinc: Located in East Town, lead and zinc metal reserves of about 1800 tons; ⑵ Yang Chong (lime punch) lead-zinc : Located in Sin Town, lead and zinc mines of the best mineral, deposit types, mostly quartz veins of lead, galena, sphalerite, pyrite and other minerals; ⑶ Chen Wang Yang Bay lead-zinc mine ear: In the southern town, lead and zinc grade of 5.6%, an estimated 14,880 tons of lead and zinc metal reserves; ⑷ ??Gan Village mine, in the town of smoke, containing pyrite mine is very high; ⑸ cross rock pond Pb-Zn: In Zhe Town the territory has been mined by the local commune; ⑹ Jiangnan lead and zinc: Located in the southern edge of the town rushed Village kiln industry, ore mainly galena, sphalerite, the average lead content of 18%, the geological reserves of 4,020 tons; ⑺ Hibiscus tip Yan Chong lead and zinc; Rock Bottom is located in the village of Muzi estimated 243 tons of zinc metal reserves, 77 tons of lead; ⑻ Lin Chong maple side lead and zinc: Town Forest is located in East Village with iron slag machine , ore fineness of about 20%; ⑼ unitary state pears slope lead and zinc: Town unitary state in the East Village, lead-zinc veins exposed in pears slope streams, the pure lines green sand; ⑽ yellow Shaxi lead and zinc: Located Kui Creek Huang Shaxi Town, ore reserves of 45,000 tons; ⑾ concept of lead-zinc mine head: Located Kuribayashi Township, galena, sphalerite, stibnite, pyrite and other metal widely distributed, with "308" roadway for example, the ore of lead was 1.09%, 5.7% zinc, lead and zinc metal reserves of 420 tons. .
