Iron ore is an important raw material of steel producers.After crushing, grinding, magnetic separation, flotation, re-election and other procedures,natural minerals
Gold occurs principally as a native metal, usually alloyed to a greater or lesser extent with silver, or sometimes with mercury. Native gold occur as sizeable nuggets,
Lead and zinc ore is the metal-rich mineral elements such as lead and zinc, blue gray, hardness 1.5, it is the most soft metals, lead is one of the earlier extracted in history, lead and zinc are widely used in various of areas.
Magnetite ore is a significant ore of iron, it is black or brownish-black with a metallic luster, has a Mohs hardness of 5–6 and a black streak. Magnetite ore beneficiation process is divided into crushing, grinding, classification, magnetic separation, dry tailings discharge, three phases.
Silver is commonly extracted from ore by smelting or chemical leaching. Silver mining is the resource extraction of silver by mining. Silver ore beneficiation first choice is large capacity magnetic separation, followed by is electrostatic separation, and then re-election, and the minimum is flotation.
Quartz main ingredient is silica, Mohs hardness 7, translucent or opaque crystals, generally white.Quartz according to the quality can be classified of ordinary quartz sand, fine quartz sand, high purity quartz sand and fused silica sand. Quartz stone production line is divided into ordinary quartz sand quartz sand and refined quartz sand. General quartz sand specifications: 6-10mm ,10-20mm ,20-40mm ,40-80mm ,80-120mm, 120mm, 200mm, 260mm, 325mm, 600mm.
Gypsum is usually white, colorless transparent crystals, when impure ingredients can be dimmed, red, yellow or black. Hardness is 1.5-2. Specific gravity is 2.3. With flexibility and flexibility. Gypsum is a widely used industrial materials and building materials. Retarder for cement, gypsum building products, model making, medical food additives, sulfuric acid production, paper fillers, paint fillers.
Calcite Mohs hardness is 3, calcite belongs to easy to grinding ore type, calcite milling generally require ultrafine calcite powder fineness, therefore, calcite is generally use fine powder grinding mill machine to grinding. Calcite mill general finished size range is 325-2500 mesh, production capacity is about 900-6000kg/h or so.
Slag is discharged during steelmaking, usually dark and dark brown. By steelmaking furnace slag can be divided into flat slag, electric furnace slag, Slag is mainly content calcium, iron, silicon, magnesium and a small amount of aluminum, manganese, phosphorus and other oxides. It is a large displacement of industrial solid wastes, discharged crude steel production is about 15% -20%.
The main mineral component of limestone is calcite. It has rare crystal structure and mineral particles and its surface is smooth and granular. Colors are black, gray, white, yellow and brown. Limestone containing seawater formation lime, hence the name of marble, limestone, chalk, rock, etc. Their main component of natural mineral is calcium carbonate.
Pebble is a natural stone from the sand mountains generated by the uplift of the ancient river bed which has experienced the earth movement thousands of years ago. They have gone through the impact of the flash floods and the continuous extrusion, friction in the water movement. They were beat by wave and water again and again. Finally, they were buried deeply in the ground for thousands and millions of years.
Basalt main component is silica, aluminum oxide, iron oxide, calcium oxide and magnesium oxide. Common basalt is black, dark brown or dark green. Because of its dense texture, its specific gravity is heavier than granite, limestone, sandstone, shale. There is also light porous basalt, called "pumice."
Granite is a common type of intrusive, felsic, igneous rock which is granular and phaneritic in texture. This rock consists mainly of quartz, mica, and feldspar. Granites sometimes occur in circular depressions surrounded by a range of hills, formed by the metamorphic aureole or hornfels.
Coal is very important energy source, and also an important raw material for metallurgy and chemical industry, there are lignite, bituminous coal, anthracite coal, semi-anthracite. When the coal seam close to the surface, it’s called open pit mine and about 40% of world coal production use pen pit mining. Seven largest coal reserves countries are the United States, China, Australia, India, Germany, South Africa and Poland.
Talc is a common silicate minerals, it is very soft and has a creamy texture, talc Holmes hardness is 1. Generally talc is blocky, leaf-like, fibrous or radial, color is white, gray, and will contain other impurities due with various colors. Talc has many applications, such as refractories, paper making, rubber filler, pesticide absorbers, leather coatings, cosmetic materials, carving materials and so on.
DMAN Jaw Crusher
