Chemical Separation

The chemical separation method is the most commonly used method for separating molybdenum and copper. This method is based on the difference in solubility of molybdenum and copper in various acids. The most commonly used acids are sulfuric acid, hydrochloric acid, and nitric acid. The process involves mixing the molybdenum and copper materials with acids and then separating them by means of sedimentation or filtration.

Advantages of chemical separation:

Simple process

High purity products

Disadvantages of chemical separation:

High cost

Environmental pollution

Physical Separation

Physical separation is based on the difference in physical properties between molybdenum and copper. This method includes froth flotation, magnetic separation, and electric separation. Froth flotation is based on the difference in surface wettability of molybdenum and copper minerals. Magnetic separation is used to separate magnetic and non-magnetic fractions of molybdenum and copper minerals. Electric separation is based on the difference in electric conductivity of molybdenum and copper minerals.

Advantages of physical separation:

No chemicals used

Environmentally friendly

High purity products

Disadvantages of physical separation:

Low recovery rate

High cost

Electromechanical Separation

Electromechanical separation is a process that uses electricity to separate molybdenum and copper minerals. This method includes electrolysis, electric arc melting, and Hall-Héroult process. Electrolysis is based on the difference in ionization tendency of molybdenum and copper minerals. Electric arc melting and Hall-Héroult process are based on the difference in melting point of molybdenum and copper minerals.

Advantages of electromechanical separation:

High recovery rate

Environmentally friendly

High purity products

Disadvantages of electromechanical separation:

High cost

Technical complexity

In conclusion, chemical, physical, and electromechanical methods can be used for separating molybdenum and copper effectively. However, each method has its own advantages and disadvantages. The most suitable method depends on the specific circumstances, including the type of ore, processing requirements, and environmental conditions.
