Iron Ore Processing

Iron ore introduction:

There are more than ten kinds of iron minerals in nature.Industrial iron minerals are mainly magnetite, hematite and imaginary hematite;followed by siderite, limonite and so on.Iron ore is an important raw material for steel producers. Natural iron ore is gradually selected from iron after crushing, milling, magnetic separation, flotation, and re-election.

Applicable materials:

Processing of non-ferrous metal minerals such as iron ore and gold ore

Equipment configuration:

Jaw crusher, cone crusher, vibrating screen, belt conveyor

Iron ore processing:

Dewo produces mineral crushing line equipment and provides technical support,mineral crushing processing usually consists of vibration feeder, jaw crusher, hydraulic cone crusher, vibrating screen, belt conveyor and other equipment;It is suitable for the processing of non-ferrous metal minerals such as iron ore and gold mine; the designed output is generally 50-1000 t/h.

Iron ore beneficiation, depending on the type and nature of the ore, can have a variety of different processes. The ore dressing plant generally uses a coarse, medium and fine broken three-stage crushing process to break the iron ore. The coarse and broken multi-purpose jaw crusher uses a cone crusher for medium and fine crushing. Through the coarse ore, it is then finely divided into fine particles suitable for entering the ball mill.

The ore is evenly sent to the jaw crusher by the vibrating feeder for rough breaking.The coarsely broken material is sent by a belt conveyor to a coarse cone crusher for further crushing.The broken material is sent to the vibrating screen for screening.The material that meets the particle size requirements of the finished product is transported to the finished product pile by a belt conveyor;Materials that do not meet the particle size requirements of the finished product are returned to the broken or finely divided cones from the vibrating screen to form a closed loop.Finished product granularity can be combined and graded according to user needs.

Iron ore processing technology:

The iron ore beneficiation crushing production line has high degree of automation, high breaking rate, low operating cost, energy saving and environmental protection, and fine grain size.

The production line is mainly based on the actual material size and the customer’s requirements for product granularity. According to different production site conditions, Dewo engineers can provide customers with process planning and technical support, and we can also design non-standard according to the actual installation conditions of customers and supporting components, etc., we strive to achieve a reasonable and economical production line for customers.

Copper Ore Processing

Copper ore introduction:

The copper ore beneficiation production line generally adopts a relatively simple process.After a period of grinding, the fineness -200 mesh accounts for about 50% to 70%,1 rough selection, 2~3 selections, 1~2 sweeps.If the particle size of the copper mineral is relatively fine, a stage grinding process may be considered.Most of the concentrating plants that deal with the porphyry ore are selected by the coarse ore re-grinding stage.The essence is the hybrid priority flotation process.

Equipment configuration:

vibrating feeder, jaw crusher, impact crusher, ball mill, spiral classifier, magnetic separator, flotation machine, concentration barrel and dryer, etc.

1. Broken part: The basic process of crushing the ore process. The purpose is to crush the ore to an appropriate size and is suitable for grinding a part.

2. Grinding part: The 0-12 mm copper powder sieved through the vibrating screen is evenly sent to the scoring mill for grinding and pulverizing. The ore is further processed to obtain a smaller size for the flotation separation material.

3. The ore fines ground by the ball mill enter the next process: classification.The spiral classifier cleans and classifies the ore mixture by the principle that the specific gravity of the solid particles is different and the rate of precipitation in the liquid is different.The washed and graded mineral mixture separates the magnetic material in the mixture by magnetic force and mechanical force when passing through the magnetic separator because of the different specific magnetic susceptibilities of the various minerals.The mineral particles that have been initially separated by the magnetic separator are sent to the flotation machine, and different drugs are added according to different mineral characteristics, so that the desired minerals are separated from other substances.After the desired minerals are separated, the dried copper tailings can be obtained because they contain a large amount of water and are initially concentrated by a thickener and then dried by a dryer.
