Recycling design of sericite in tailings

Large metal ores are considered low-grade ore, particularly a lower precious metal ores, non-ferrous metals grade, produced more than 90% of solid waste such metal ores in the mining, mineral processing, metallurgical processing and production process. In particular, the beneficiation tailings are

Pilot process of pyrite cinder spiral chute-shaker

The pyrite cinder (dry mine) is sieved through a 100 mesh sieve, and the sieved product is ground in a rod mill for 5 min, the grinding concentration is C=70%, stirred for 5-8 minutes, and then re-elected by a spiral chute. The obtained tailings were further shaken to obtain the middle and tailings

Comprehensive utilization of gold mine tailings

At present, China has more than 200 kinds of gold mining vessels, with an annual excavation volume of more than 70 million cubic meters. The annual bank tailings of the onshore selection plant matched with gold mining vessels amounted to 252,000 tons. These magnetic iron ore tailings contained, hem

Nickel oxide

Nickel oxide is a green powder. When it is overheated, it is a powder with a specific gravity of 6.6 to 6.8 and a melting point of 1990 °C. Do not dissolve in water and liquid ammonia. Soluble in sulfuric acid, nitric acid, hydrochloric acid and ammonia. It is oxidized to nickel oxynitride in ai

Magnetic selection job duties

1. Under the direct leadership of the squad leader, complete the magnetic separation post operation according to the operation rules, technical cards and various rules and regulations of this post. 2. Familiar with the contact between the post and the upper and lower operations to ensure smooth se

Solid fuel combustion (1)

(1) Combustion reaction and its thermodynamic analysis The fixed carbon content of the fuel for sintering is generally 68-80%, and it can be burned when the temperature rises above 700 °C. When sintering is ignited, the ignition temperature should be between 1100 and 1200 ° C because the surf

Effect of associated minerals on cyanidation

Gold ore mineral composition is varied, in addition to inert, non-functioning cyanide mineral (quartz, silicates, iron oxide), the oxygen can often present with cyanide and reacting the starting solution. They carry out side reactions, increase the consumption of reactants, and reduce the rate of l

Treatment and recovery of soot and arsenic trioxide

For some of the pyrite-type arsenic pyrite gold ore leaching difficult, in addition to the firing process flue gas SO 2 is generated, there are dust, arsenic, mercury, cadmium, lead and other harmful elements, so the addition of SO 2 while, These harmful elements should be treated. 1. Treatment an
