Common knowledge of mineral processing

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

图片
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 to reduce the dust of jaw crusher

图片
How to reduce the dust of jaw crusher ? Source of jaw crusher dust Dust is initially caused by ore crushing, part of which is carried by the ore itself, and part of which is generated in the later stage of ore crushing.The general movement trajectory of the ore is as follows: the ore enters the machine from the feed port, is broken to the relevant particle size in the machine, is discharged from the discharge port, and then is transported to the next section of processing equipment by the belt conveyor.It can be seen that the devices that directly contact dust with air are inlet, outlet and belt conveyor.In addition, the use of hopper, protective cover, chute and other materials in the production process will produce a certain height difference, which is another major cause of dust. To solve the problem of jaw crusher dust , the first is to control the dust source with the help of external force to avoid its diffusion, and the second is to improve the local structure of the machin...
