Full mineral processing equipment line

What is the application of mineral processing in ore extraction?

Mineral processing means crushing, milling, beneficiation and so on, which is in order to separate mineral and gangue with each other maximum, and then get high grade concentrate. The main object of full mineral processing equipment is natural ore, and secondary resource such as tailings, surrounding rock, industrial and subsistent wastes.

The purpose of full mineral processing machine is to remove gangue and harmful element in the mineral, enrichment or separate different valuable mineral by each other, get one or several concentrate product.

Generally, primary ore can't be used as metal or product directly, they should be processing by whole mineral beneficiation equipment, such as raw iron ore grade. So mineral processing is very important role during mineral resources rational utilization and development of national economy.

The purpose of mineral processing is the following

1. Enrich useful mineral components.

The lean iron ore with about 30% added iron can be beneficiated to obtain an iron concentrate with more than 30% added iron, and the useful mineral magnetite is enriched.

2. Separate two or more useful mineral components.

For example, sulfides of copper, lead, and zinc often coexist together, and they can be separated through mineral processing to obtain copper concentrate, lead concentrate, and zinc concentrate respectively.

3. Remove harmful impurities from materials.

For example, some or most of the harmful impurities sulfur and phosphorus in iron concentrate can be removed through beneficiation. In addition, the iron and titanium minerals in kaolin that affect its whiteness can be reduced through beneficiation to meet the required standards.

What method to process minerals?

Method of full mineral processing mainly divides into two types, physical and chemical.

Physical method contains magnetic process, gravity concentration and so on.

Chemical method contains flotation, roasting method, lixiviation process, etc.

What are the commonly used equipment in mineral processing production lines?

Commonly used mineral processing equipment mainly includes crushing equipment, grinding equipment, screening equipment, mixing equipment, flotation equipment, drying equipment, etc.

Crushing equipment: Commonly used crushing equipment for copper ore processing mainly include coarse jaw crusher and fine jaw crusher. Feeding equipment before crushing - vibrating feeder, trough feeder, etc.

Grinding equipment: Commonly used grinding equipment for copper ore processing mainly include beneficiation ball mills, dry ball mills, wet ball mills, grid-type ball mills, high-efficiency ball mills, etc., as well as swing feeders, electromagnetic vibration feeders and belts that feed the ball mill. Conveyors, etc.

Screening equipment: Commonly used screening equipment for copper ore processing mainly include spiral classifiers, high-frequency screens, linear screens, etc. They are often used in conjunction with ball mills to form a closed loop.

Stirring equipment: The commonly used stirring equipment for copper ore processing is the mining mixing barrel. Its main function is to stir, add water and chemicals before the slurry enters flotation.

Flotation equipment: The flotation equipment commonly used in copper ore processing is a flotation machine. Commonly used ones include x-water K-type flotation machine, Sf-type flotation machine, etc.

Drying equipment: Drying equipment is often used for dehydration of copper ore concentrates. Commonly used dehydration and drying equipment for copper ore processing include drum dryers, thickeners, dehydrators, etc.
