Xinhai has been a gold separation machine manufacturer for decades years, gold separation technicals and gold separation methods provided by Xinhai can separate gold from raw ore.
1. Single flotation of gold separation techniques and gold separation methods
This kind of gold separation techniques and gold separation methods is used to separate coarse and middle gold ore. The gold ore is crushed and ground to the pointed particle size and the gold ore grinding equipment feeds it to the gold ore flotation cell with the sodium carbonate as a modifier and the butyl xanthate and butylamine aerofloat as a collector to separate the useful minerals and gangue minerals by the different hydrophobic of the mineral surface.
2. Flotation with HG of gold separation techniques and gold separation methods.
This kind of gold ore flotation is used to separate natural minerals with coarse particle size and associating with pyrite and other sulfide ore. What is different from the single flotation is that the slurry should be added the Hg after grinding in this kind of flotation separate. This method is called adding Hg in the ball mill that is to say while grinding the minerals, the Hg will be added to extract the gold. Another method is adding the Hg outside the ball mill to extract the gold. The Hg spreads in the gold particles to form the solid solution finally. When heating the solid mercury, the sponge gold will be got.
3. Gravity separation method of gold separation techniques and gold separation methods.
This gold separation techniques and gold separation use the different gravity of gold and other minerals to achieve the separation. The bigger difference of the minerals is, the easier of the separation will be. Usually, after the vibrating screen, jig and concentrating table, the ore with gold will become the gold concentrate. this gold separation techniques and gold separation methods should use gravity separation gold ore separation method which is commonly used in the quicksand. Also, the minerals after crushing can also use this method.
4. CIP (carbon in pump) of gold separation techniques and gold separation methods.
The ore is ground to a certain particle size and then it will be leached. When it is leaching, the activated carbon will be added to it to improve the leaching rate of the gold. Finally, the gold ore separation techniques and gold ore separation methods need the carbon with the gold will be got. Using high temperature to remove the gold in the carbon. Then the electrolysis method will be used to purify the gold during which some measure will be taken to recycle the tailing and the gold in the leaching liquid.
5. Microbial leaching of gold separation techniques and gold separation methods.
This gold ore separation techniques and gold ore separation methods are usually used in the ore with low quality of gold and in the mine with large stone capacity. The sulfur mine such as iron sulfide in the ore wraps the gold which prevents the reaction between the cyanide leaching and gold ore. Before leaching, the microorganism such as ferrooxidans will be used to resolve the sulfur mine in the surface of the gold. At the same time, the cyanide in the bacterial liquid reacts with the gold making it enter into the leaching liquid. Then the gold in the leaching liquid will be recovered.
There are two gold ore separation techniques and gold ore separation methods that are directly smelting and electrolysis smelting will be used to remove the impurities from the concentrate above. Then the gold will be left.
>Based on the material nature, pulp capacity and product density, we choose the thickener specifications. For small dressing plant, the pulp capacity is low and it can use a miniature thickener. ... [more]
