Gold mining machinery in China and hematite beneficiation process

Gold mining machinery for sale in USA

Gold ore processing plant in gold mining consists of crushing, screening, grinding, washing and so forth. The large gold ore crushing products in the processing plant are: gyratory crusher, hefty duty jaw crusher, CS series cone crusher, HP cone crusher and so on. ZENITH is usually a specialist gold mining machine manufacturer&supplier of gold ore crusher and gold mining crusher and gold mill machines. In gold mining, high technology gold mining products, such as gold detectors, elegant modern dredges, and lightweight sluices will be needed. Gold crusher also refer to jaw crusher. Jaw crushers is the most common gold mining tools, and is designed to take significant rocks and partially crush them down to a more workable size.

1. Crushing equipment

Within the crushing course of action, it could be divided into two crushing stage: the primary crushing and secondary crushing system. Jaw crusher is employed inside the main crushing method. Mined gold block ores are sent into jaw crusher evenly by means of vibrating feeder for that initial crushing approach. The gold ore will be crushed into small size. Then belt conveyor will get the supplies into cone crusher or affect crusher for more crushing.

2. Grinding equipment

When the crushing course of action is not going to attain the manufacturing necessitates, grinding mill will grind the crushed supplies into fine dimension or ultrafine size.

3. Beneficiation equipment

The goal from the whole gold mining machinery in China is usually to have the higher grade and pure gold ore. The quite first two stages just break the raw products, however the impurities typically don’t do away with. To take away the impurities, it seriously is very vital to produce utilization of the beneficiation products. Flotation machine, gravity separator and magnetic separator will probably be adopted to clean gold ore. Inside the complete mining course of action, auxiliary tools assists the important thing mining products to complete the entire mining course of action.


The haematite’s a different identify is red iron ore, and its chemical structural formula is Fe2O3. It’s a weak magnetic iron ore as well as floatability is greater than magnetite. And it is a primary materials of ironmaking. The main beneficiation method consists of: gravity separation, floatation, sturdy magnetic beneficiation or combine quite a few beneficiation procedure, and another approach is magnetization roasting and then weak magnetic separation. The early haematite beneficiation typically used the gravity separation method, plus the primary machines are: jigger, centrifugal separator, spiral chute, spiral washing machine, shaking table and so on. Because some other beneficiations’s manufacturing capacity was tiny, the grade after processing was reduced, recovery ratio is reduced and then was dumped as time goes on. Later on as the haematite beneficiation building, the floatation method ans higher intensity magnetization process. It mostly use oxidized paraffinum sodium salt because the collector for floatation and electromagnetic solid magnetic separator as beneficiation gear for powerful magnetic separator. However the other folks beneficiation engineering target had been all not very good adequate. These most recent many years, the beneficiation procedure of haematite has designed extremely well. In particular make use of the substantial intensity magnetic separation that is can improve the grade of iron ore focus extremely nicely,and also the recovery of Iron ore concentrate is satisfying.

In gold ore mining approach, the crushing plant and also the auxiliary products would be the crucial factors to meet the production specifications even though trying to keep capital and operational fees to a minimal. The basic aim of Zenith’s gold ore crushing plant will be to meet the manufacturing necessities, operate at aggressive expense, comply with today’s hard regulations and may be constructed at a reasonable selling price in spite of the increasing expenditures of tools, power and building labor.

The crushing plant of Zenith includes the following gear: vibrating feeder, jaw crusher, impact crusher, gold ore washing plant, cone crusher, vibrating display and belt conveyor and so forth. Zenith designs distinct crushing plant ranging 50t/h to 500t/h by combining distinct versions to meet various customers’ technological necessities.

Hematite beneficiation process

Beneficiation could be the system the place ore is decreased in size and gange separated in the ore. Because all iron ore deposits have exclusive mineralogy, the beneficiation course of action is distinct to each deposit. Separation of certain minerals is usually effectively attained by taking benefit in the physical, electrical and magnetic properties.

Zenith supplies a comprehensive array of test get the job done solutions for your minerals sector. Our substantial worldwide network of laboratory and metallurgical testing amenities assistance most of the processes that are used within the exploration and remedy of most metals and commodities globally. All physical separation procedures may be tested at Zenith, both around the laboratory and pilot plant scales.

Hematite crushing process

The hematite beneficiation process ore easy to elect hematite, ore crushing to-25mm particles mixed to magnetic separation towards the ore bin, the discharged ore mixed with water for the ore bin in to the shaker to feedend sieve 1mm, ore discharge finish 6mm,greater than 6mm fraction is usually given towards the roll crusher crushing, then returns screening, may also be sent directly towards the open yard of greater than 6mm, the fraction yield of seven.3%, grade of 65%.

Hematite grading and magnetic separation

Hematite 1mm-6mm of size fractions is dehydrated? with dewatering screen to the concentrator ore bin since the final concentrates, iron 68%.-1mm 0mm hematite resources, the classification in the hydrocyclone into-1mm-+0.15 mm-0.15mm-+0.02 mm-0.02mm 3.The initial two ranges before the magnetic separation management sieve, sieve items are sent towards the ore bin 1mm-6mm level merchandise as concentrates.Undersize product will go into a robust magnetic separator sorting.-0.02mm slime is abandoned.Magnetic separator focus manufacturing fee is 65%, 68% grade, thickness of two levels of iron in the total recovery of 89% and the complete recovery with the entire plant was 78%, 8% -10% from the magnetic separation tailings iron, mineral magnetic separation rate10%, grade of 48%, return to the re-election.
