subject: Flotation Is The Best Way To Dressing Gold Ore [print this page] Structural state and gold minerals gold, gold deposit minerals into gold minerals, gold-bearing mineral and gold-bearing mineral three categories. Independent minerals of the so-called golden means the output of gold minerals and gold minerals in the form of gold, it is the nature of gold in the most important occurrence in the form of industrial development and utilization of the main object.
Mainstream for gold extraction process, generally through the crusher broken into the ball mill grinding, re-election, flotation, concentrate and tailings extracted by chemical method, and finally after smelting, and its products eventually become the finished gold.
The flotation is the most widely used as a dressing method with gold production. Differences in physical and chemical properties of mineral surfaces to choose a method of sub-ore. A flotation history and development of ancient Chinese have used naturalmineral surface hydrophobicity to purify the mineral cinnabar, talc and other drugs, mineral powder floating on the water without the waste rock particles sink.
Flotation can choose to close the fine-grained differences in physical and chemical properties of mineral surfaces, and even micro-fine minerals. The ultra-fine particles flotation or charge carrier flotation and ion flotation recovery of micro-fine gold. Before liberation, China has several gold flotation plant and byproduct recovery of gold and non-ferrous metal flotation plant.
Gold flotation process has been widely used in gold concentrator, even if it is a small village and township mines and artisanal gold per household successful election received gold in the use of flotation. Flotation even the principle mineral particles surface with hydrophobic or flotation agent role or enhanced hydrophobicity. Hydrophobicity is pro-oil and pro-gas, liquid, gas or water - oil interface aggregation. After a series of treatments with gold grain density was able to with bubbles and flotation agents affinity while floating on the ore fluid surface of the flotation machine, foam products recycling. This is a way to gold flotation. It is suitable for sorting 0.5mm to 10um of gold particles. When selected mineral particles less than l0um special flotation. Useful flocculants to make fine gold or gold-bearing mineral flocculation into larger particles, prolapsed of the gangue of fine mud and then float to coarse-grained gangue, flocculation - flotation. The Dutch carrier flotation of mineral particles with particle size suitable for the load carrier, so that the adhesion of micro-fine gold in the surface of the charge carrier and with the float is made of gold concentrates. Reunion of fine ore particles with oil so that oil agglomeration flotation and emulsion flotation. The use of high-temperature chemical reaction of metallic minerals in the ore into the metal after the flotation segregation flotation gold ore seldom used. On the use of foam flotation recovery of gold mud, China will be used in industrial fields.
