One of the in underground is called room and pillar, and is often for coal. Part of the is open to the surface and part of it is underground. The coal face is dug out, but pillars of coal are left behind to keep the tunnels open and support the roof. called continuous miners are to remove the coal.Leave Us Now

Flotation 【Capacity】 0.18-20m³/min per cell 【Feeding size】 200 mesh no less than 80% 【Application】 sulfide, gold sulfide, zinc, lead, nickel, antimony, fluorite, tungsten, and other non-ferrous metals, and also be for coarse selection for ferrous metals and nonmetals.
Commonly beneficiation include gravity , flotation, magnetic , electrical and chemical beneficiation. Even the same type of , it is necessary to design the most appropriate process according to local conditions, and cannot be copied completely.
The commonly is , jigger, shaking table, chute, centrifuge. Gravity can handle placer and gangue minerals. Gravity equipment is a simple structure, convenient maintenance, low production cost, and small pollution to the environment is obvious, Gravity is still one of the most important ...
· is most commonly in the industry to separate “tramp ” or unwanted waste metals, from the rest of the bulk material.
We this for platinum. Large scale mechanised we include: long-wall , where a long wall of coal is mined in a single slice, usually by a large . sub-level-caving, where levels of the are blasted by explosives and

In general, the Tungsten processing of heavy selection is generally , and the dressing of Tungsten with a high degree of dissociation of the monomer is basically the same as the dressing of gold ...
Copper ore divides into ore sulfide ,ore oxide and mixing ore according to its oxide rate . The main process for copper ore is flotation , for refractory mixed copper ore and refractory oxide ore , normally use process .It is a high technological enterprise that integrated research , manufacture, sales and service .
When rich enough, native copper ore bodies may be treated to recover the contained copper via a gravity separation circuit where the density of the metal is used to Often, the nature of the gangue is important, as clay-rich native copper ores prove difficult to liberate.
Because the Bessel process was on graphite not gold, silver, , lead, zinc, etc, their work has been ignored by most historians of the technology.  Inventor Hezekiah Bradford of Philadelphia invented a " of saving floating material in - ” and received US patent No. 345951 on July 20, 1886.
Panning and the traditional are examples of gravity . Shaking Tables such as the well-known James table are fitted with ridges similar to the riffles in a . is washed over the vibrating table and the desired heavy mineral is trapped by the ridges and flows along them to a collection launder whilst gangue flows over them.
The process to treat sulfide begins at the site, where the copper-bearing minerals are physically separated from the rest of the rock. The flow diagram below shows how the percentage of increases as the is refined, first physically by froth flotation, then chemically by smelting and finally electrolytic refining.
During gravity separation, heavy medium or jigging methods are commonly used for the gravity separation of coarse and very coarse >20 mm ores spiral chutes, shakers and for medium to fine 2~0.2mm ores, etc. Reselect method. In magnetic separation, the strong magnetic separator of coarse and medium-grained ore is usually dry-type strong magnetic …
