Cobalt is associated with iron , copper and nickel ore. There are mainly four kinds of cobalt ore in China: copper nickel cobalt ore, copper cobalt ore, iron cobalt ore and cobalt ore. Different beneficiation methods are required for different main minerals.
Copper nickel cobalt ore
The cobalt in the ore is similar to copper and nickel in the same mineral. In the process of beneficiation, nickel and cobalt cannot be separated. Therefore, it is not necessary to design a separate process for selecting cobalt-containing minerals. The selected concentrate is cobalt-containing. Copper-nickel concentrate and cobalt-containing nickel-containing sulfur concentrate, which is recovered in smelting anode electrolytic sludge and slag.
2. Copper-cobalt ore
This ore production mainly Shanxi Zhongtiaoshan non-ferrous metals company Grate ditch, Hubei Daye Nonferrous company recorded a mountain of copper and Huili Lala plants and other mineral deposits. The main cobalt-containing minerals are sulfide minerals such as chalcopyrite, pyrite and pyrrhotite. The chalcopyrite can be separated from the latter by flotation to produce copper concentrate and cobalt-sulfur concentrate. A small amount of cobalt can still be recovered from the anodic electrolytic sludge of the smelting copper concentrate.
3. Iron cobalt ore
The minerals produced in this area include Zibo North Jinzhao North, Shandong Jinling Tieshan, Shandong Laiwu Iron Mine and Hubei Huangshi Tieshan. The main cobalt-containing minerals are pyrite minerals such as pyrite, pyrrhotite and a small amount of chalcopyrite. The flotation method can be used to separate the sulfide and magnetite, and then a small amount of chalcopyrite and pyrite and pyrrhotite are separated by flotation, and magnetite is separated by magnetic separation to produce copper concentrate. , cobalt-sulfur concentrate and iron concentrate. Sulfur is a harmful component of iron making. Such ore must be selected before it enters the furnace. Therefore, mines with selected plants generally have a flotation process. Therefore, such mines can recover cobalt and sulfur concentrates.
4. Cobalt ore
Hunan Changsha Xialuping Cobalt Mine is currently mined by township enterprises and recycled by Hengyang Smelter. Hainan Andingju Dingcobalt Mine has a high grade of ore and a cobalt grade of 1.632%. Currently, a cobalt company is designing and preparing for mining. Its cobalt-containing minerals are mainly hydroxides and aqueous oxide hydroxides. According to the results of the relevant ore dressing experiments, it can be produced together with the Hailu Shilu copper-cobalt mine and can be exploited in the open pit.
Granulator is mainly composed of feeding, mixing, pelletizing, transmission and lubrication system. Its working process is to require powder with water content less than 15%. It enters the feeding winch from the hopper. By adjusting the speed of stepless speed regulating motor, it obtains the appropriate material flow rate. Then it enters the agitator. It is conditioned by stirring and mixing with steam through the stirring rod. If molasses or grease need to be added, it is also added from the stirring barrel. When steam is tempered together, the amount of oil added is generally not more than 3%, otherwise it is difficult to form. After tempering, the temperature and humidity of the powder can reach 64-85 C and 14-l 6%. Then the iron impurities mixed in the powder are removed through the inclined groove through an optional iron absorption device, and finally the granulation is carried out in the pressing chamber.
Scope of use
1. Pelletizer is a kind of swing action of rotating drum. It can grind wet powder materials into granules through wire sieve, and it can also be widely used to crush the granules that have become blocks and become ready-made granules.
2. In chemical medicine, it is used to grind wet powders into granules, dry them for pressing tablets, crush the caked cakes during storage or during chemical processing, treat confectionery and sugar mixtures, malt milk and other products in food industry, and mix ceramics and plastics in other industries. The mixture becomes the molding granule.
3. it is not suitable for semi-solid, fluid, slurry or wear.
