Beneficiation theory of chrome oremining plants: after crushing by the crushers, chrome grains are liberated or dissociated from the gangue and the mixed ore can be fed to the separation processing for the secondary processing stages.Chromite ore beneficiation machines are allocated according to the specific natures of the chrome ore.The main methods for chrome beneficiation are mainly gravity separation and magnetic separation.And the chrome beneficiation machines are also mainly gravity separators and magnetic separators.So at the beneficiation process, the equipment are quite different from each other because the chrome concentrating methods are different for different chrome ores.Many methods can be used in chrome ore beneficiation plants.The mainly chrome ore beneficiation method is gravity-separation.The mainly chrome ore concentrating equipment are ore washing box (called jigger), table concentrators, spiral chute, etc.Usually, the chrome ore can be upgraded by jigging machines firstly, and then the shaking table can be used for secondary upgrading as fine selection to get final high grade chrome concentrate.
Grinding: after crushing the stone to a smaller size, need to grind to power by tin ore ball mill grinding machine or wet pan mill or other rock grinding machine, so the tungsten concentrate can be released out from stone.Then go to the gold separation machine and concentration machine( tungsten ore shaking table).
The shaking table is a gravity dressing machine used for separating fine particles.They are mainly used for various metals such as gold, silver, zinc, tungsten, iron, manganese, lead and coal and heavy metal materials.It is suitable for different grades of materials such as 2-0.5mm, coarse sand of 0.5-0.074mm, fine sand, and slime of 0.074mm.When the beneficiation shaker processes tungsten or tin metal ore materials, the effective recovery range of the equipment is 2-0.22 mm.
4.Gravity separation to remove heavy minerals it is for primary silica sand gravity separation to remove heavy minerals, such as ilmenite, hematite, iron, etc, the most common use silica sand separation machine is shaking table, spiral chute separator.It depends on the processing capacity to choose which gravity separation machine.
The working principle of the shaking table is separates the heavy material from light material by using their different proportion & specific gravity, under the effect of gravity, the minerals will divide into the ore concentrate, the middling and the tailing.The prominent advantage of the ore shaking table is precise separation.The enrichment ratio of concentrate is very good, up to 95% high recovery ratio for kinds of heavy minerals, when dealing with low-grade tungsten ore and tin ore, the enrichment ratio could reach about 300 times.
2) coated with epoxy resin layer.gold shaking tablethe methods use a more complicated, therefore the use of a wide range.
After the pseudodynamic method, the dynamic method which is finite element method and the shaking table test are used to the safe design of retaining wall in the seismic zone [15, 16].
Traditional shaking table occupies large areas, low in work capacity, great in customers' investment, which annoys customers a lot.But there is no better solution to solve these problems.Double-deck table solves many problems in the course of using single deck table.
Our factory(jxsc mine machine factory)have laboratorycan make tin sample to testing.Have jaw crusher, ball mill, vibrationscreen, shaking table, magnetic separator.Every tin mining contentis not different, if have much iron, or some with magnetismmetal, it can use magnetic separator take it out, then can improve the tin recovery rate.If for stone can grinding first then to shaking table, if the size is for 0-2mm, is can directly to shaking table for test.Our city also have testing company, after our machine testing.Can send to testing company, testing company will analyze each metal content.Every tin is different, so need make a test, then base this to make the best flow chat.
Stone tin need know the capacity and feeding size.Then base this two information to choose the machine, if the feeding size is for 0-30mm, use ball mill and shaking table, if the feeding size >30mm, need use crusher grinding first, then to ball mill grinding again.Last step use shaking table for concentration.
Diaphragm jig separator is a kind of popular gravity separation equipment, it can work great independently or work together with a shaking table.With the research and development of the jigging machine, the jig gravity separator has been very common and mode popular in these years.Jxsc mining machinery factory is a professional manufacturer of mining beneficiation equipment, has many clients with its rich chrome upgrading experience.We can do trial test for you if samples can be available.
6-sshaking table is effective in processing precious and base metal, rare metal and non-metallic minerals, widely used in separation for gold, ilmenite,silver, tin, cassiterite,columbium, tantalum-niobium, rutille,coal,titanium, barium, tungsten, iron, chrome, manganese, zircon, lead, zinc, mercury, copper, aluminum, etc.The range of effective separating particle size of shaking table is 2 to 0.022 mm.And other low-grades or non-metalic minerals which have enough specific gravity difference.
