Spiral classifier, as one of the important machines for ore separating, consists of transmission, spiral, groove, elevator, bearing bush and ore discharging valve.
The multi-cylinder hydraulic cone crusher is a special equipment for hard rock crushing.
Shaking table is a kind of ore separating machines, mainly for separating ores like tin, tungsten, gold, silver, lead, zinc, tantalum, niobium, iron, manganese, titanium and coal, etc.
Cone crusher is the machine that is made up of two cones. Cone crusher is suitable to crush medium-hardness or harder ores and rocks.
The Vibrating Screen is called circular vibrating screen because of its movement trajectory similar to a circle.

Nov 14, 2020018332The extraction of iron from its ores is quite a technical process. The iron ore is first roasted in air to produce ironIII oxide which is mixed with coke and limestone and then further heated to a very high temperature in a blast furnace. These materials are loaded into the blast furnace from the top while a blast of hot air is introduced into it from beneath via small pipes known as tuyeres.Read More

Iron ore is obtained in the conventional method of open cast or underground mining and conveying the ore to the surface preparation are where it is crushed, washed, and transported to the smelter. Here the ore is put into a blast furnace along with limestone and coke and subjected to hot air blasting and heat which converts the ore to molten iron.Read More
Mining, Ore, and Metals Mining involves the extraction of valuable minerals or other geological materials from the earth or from an ore body, vein, or seam. Materials recovered by mining can include base metals, precious metals, iron, uranium, coal, diamonds, limestone, oil shale, rock salt, and potash. Any material that cannot be grown through agricultural processes or created in a laboratory or factoryRead More
