How to Identify Industrial Value of Ore

Let us take the silicon calcium apatite for example, this type amount of this ore is less , which is characterized gangue minerals consisting of silicate and carbonate minerals, phosphorus-containing minerals are fine-grained apatite coarse phosphorus Greystone. Due to the presence of carbonate minerals than siliceous apatite ore,it is more difficult to choose. Apatite and carbonate minerals belong to the same type of cationic, which is available with the anionic collector to make it float the two similar Flotability. Apatite and carbonate minerals separation is more difficult.

Ore flotation of this type is generally used effective inhibitors of the carbonate, or increasing the amount of sodium carbonate in order to obtain a better indicator. Take the Henan Hongxing Machinery phosphate rock as example: this mine company is a large-scale mining joint ventures. Commission phosphorus plant production capacity is large, high degree of mechanization, and the production of history is long, having some production experience.

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, medium crushing and crushing. The commonly used equipments are impact crusher, compound crusher, single stage hammer crusher, vertical crusher, gyratory crusher, roll crusher machines, double roll crusher, combo crusher, 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, compound crusher. Jaw crusher (jaw crusher), having large crushing ratio, uniform particle size, simple structure, reliable operation, easy maintenance, operating costs and economic characteristics. PF-I series impact crusher can process materials side length is 100 to 500 mm, the compressive strength is up to 350 MPa, great crushing ratio, cubic particles advantages of material was broken; PF-II series impact crusher machine, suitable for crushing hard materials, such as cement crusher, with a production capacity of the material advantages of small particle size.

 
The nature of the ore mine metamorphosed sedimentary phosphate rock deposits in the case of a former Sinian marine. Phosphate rock in phosphorus-containing crystalline schist composed of mica schist, marble, manganese layer, quartz schist. The industrial value of ore types can be divided into fine-grained phosphate rock, the manganese phosphate rock layer and the mica phosphorus rock three, which fine-grained phosphate rock 80% of the total reserves. Fine-grained phosphate rock crystal fine-grained, mud, composed of the mineral apatite, calcite and dolomite, quartz, muscovite second. The manganese phosphate rock layer containing mud, soft and sticky, the constituent minerals to speak phosphonate phosphonate limestone pyrolusite, quartz, muscovite psilomelane, kaolin, etc., followed by. Mica phosphate rock crystal coarse particles, the hardness of the softer, optional. The constituent minerals mainly apatite, muscovite, quartz, limonite, hematite second.
