How is copper extracted from copper-rich ores?
Froth flotation is common, hydromettalurgy is also common.
Why is the froth flotation method selected for the concentration of sulphide ores?
This method is based on the principle of the difference in the wetting properties of the ore and the gangue particles with the water and oil. This method is used for that metals whose ore gets preferably wetted by the oil and the gangue by the water. The sulphide ores preferably wetted by the oil and the gangue with the water. Hence this method is suitable for the concentration of the sulphide ore
What process is used to separate gold from other material?
One example of the way in which an ore can be purified is the froth flotation method used with ores of copper, zinc, and some other metals. In this method, impure ore taken from the ground is first ground into a powder and then mixed with water and a frothing agent such as pine oil. Then a stream of air is blown through the mixture, causing it to bubble and froth. In the frothing process, impurities such as sand and rock are wetted by the water and sink to the bottom of the container. The metal ore does not adsorb water but does adsorb the pine oil. The oil-coated ore floats to the top of the mixture, where it can be skimmed off.
What is the separation method used in gold mining?
Gold is a kind of metallic ores . When mine gold, the flotation magnetic separation process is needed if you want to separate the gold out or if you want to improve the density of the gold. Hongj Mining Machinery is the expert of magnetic separation process, you can consult them.
What is smelting process?
A process of melting and decomposing ores to separate the metals they contain.
What is froth floation?
its a technique used during extraction of sulphide ores. sulphide ores are beated with turpentine oil. when beated, froth is produced . sulphide ores being lighter, float along with froth. froth is next separated from this mixture and the sulphide ores are too separated
How is copper extracted from copper-rich ores?
Froth flotation is common, hydromettalurgy is also common.

How can you extract mercury and copper from sulphide ores?
froth floatation
What are the various methods of concentrating ores?
They are Froth floatation, Gravity separation Hydraulic ores and Electrolytic Refining.
What is flotation in separating mixture?
In chemistry, the flotation method is used to separate substances that repel water and substances that is attracted to water. It has a variety of applications and is often used to extract mineral ores from its surroundings.

How is phosphorus obtained?
Phosphorus is obtained from phosphate deposits. Phosphate ore beneficiation methods have been continuously enriched in the development. The traditional beneficiation methods include: scrubbing and desliming process, gravity separation, flotation, gravity-magnetic-flotation combined process and roasting process. Scrubbing and desliming process: for ores with a high degree of weathering. Gravity separation: The proportion of main gangue minerals in phosphate rock is similar to that of apatite. In industrial practice, dense medium separation is mainly used. Flotation: Flotation has always been the main method for beneficiation of phosphate ore, especially for complex and difficult ores. Such as positive flotation, single reverse flotation, positive one negative (negative one positive) flotation, double reverse flotation. Roasting method: It is a fairly mature method used in industry to completely remove carbonate from phosphorite ore.

Why are ores usually concentrated where they are mined?
Economically, it makes the most sense to extract the ore that is in the most concentrated form.
