Molybdenum Dressing Production Line
Availability :
In Stock
Stages grinding and separation improves concentrate indexes Mixed roughing after the coarse grinding, then regrinding the coarse concentrate and cleaning; the small quantity of regrinding crude concentrate makes monomer dissociation and save energy consumption while obtaining high grade concentrate and high recovery rate.

Solution Description

Stages grinding and separation improves concentrate indexes Mixed roughing after the coarse grinding then regrinding the coarse concentrate and cleaning the small quantity of regrinding crude concentrate makes monomer dissociation and save energy consumption while obtaining high grade concentrate and high recovery rate.

Solution Advantages

Coarse concentrate regrinding and re-separating improves the concentrate index.

Determine concentrate regrinding and re-separating Process according to the ore properties.

To reduce energy consumption by 30 recovery rate is increased by more than 10.

Molybdenum dressing production line can be used for single or refractory molybdenum with complex properties close sulfide minerals symbiosis and fine particle distribution.

Strengthen flotation process improves molybdenum concentrate grade.Strict implementation of agent system in roughing and control agent dosage to reduce the loss of many cycles make full use of the twice enrichment of bubble washing concentrate foam to reduce the impurity in foam flotation.

Solution Case

A molybdenum dressing plant in Fujian the main valuable minerals were molybdenite. The Process of the plant was once roughing twice scavenging four times cleaning and molybdenum ore grade was 0.38. In recent years due to the mining depth increasing ore properties had changed so the flotation index became poor leading to more molybdenum metal loss. After field investigation and analysis Xinhai determined the Process according to multi tests crude one stage grinding once roughing once rough cleaning once rough cleaning concentrate regrinding three times scavenging seven times cleaning after regrinding to achieve a better index indexes comparison as follow.
