Common knowledge of mineral processing 1. What is productive rate? In the dressing process, the weight of a product and the percentage of raw ore weight, known as the productive rate. The production rate of each product is calculated as follows: Concentrate mineral rate 1=Q1/Q 100% Medium mineral rate 2=Q2/Q 100% Tail mineral rate 3=Q3/Q 100% Where Q -- raw ore weight, t; Q1 -- concentrate weight,t; T Q2 -- medium ore weight, t; Q3 -- tailings weight, t. What is the recovery rate? The concentration recovery is the percentage of the amount of metal (useful component) in the concentrate to the amount of metal (useful component) in the raw ore.This is an important mineral processing index, which reflects the degree of metal recovery, mineral processing technology and mineral processing quality.The recovery of ore dressing should be improved as much as possible on the premise of ensuring concentrate grade.The calculation method is as follows: 3. What is the Ore dressing ...
magnetic separation of quartz sand Magnetic separation is an essential process in the production of quartz sand, which has the advantage of strong selectivity. The main impurities removed are ferromagnetic minerals based on magnetite and weak magnetic impurities based on hematite, limonite and biotite.High yield of quartz sand can be obtained while removing impurities effectively. 01 Permanent magnet magnetic separator is preferred Permanent magnetic equipment has the advantages of simple structure, stable performance and low operation cost. When the permanent magnetic equipment can reach the separation index, it is best to use permanent magnetic equipment. When the quality requirement is higher or the permanent magnetic separation equipment cannot be realized, it is better to use electromagnetic and other strong magnetic separation equipment. 02 Weak magnetism first, then strong magnetism Quartz sand mixed in the crushing process of mechanical ferromagnetism is strong,...
How much is a set of quarry plant, what equipment does it use? As we all know, gravel is a common material such as construction materials and highway construction materials. The plant mining gravel is called gravel yard, and the plant processing gravel is called gravel yard or stone factory. Granite is about 120~200MPa.Primary crushing usually adopts jaw crusher , which uses the extrusion and bending effect of two jaw plates on materials, crushes the crushing machinery of various hardness materials.The secondary crushing usually adopts impact crusher to produce the particle size of materials.SHUOSEN machine to recognize 300 tons per day of 300mm counterattack crusher feed particle size, discharging size and shape can be adjusted according to customer demand for multi-functional.In addition to the impact crusher, also can choose SHUOSEN machine spring crusher, cone crusher. Main factors for equipment selection can be summarized as follows: (1) the crusher is stable with continuous fee...
