processing methods of various ores


Iron ore  :(1) ore crushing;(2) grinding process;(3) magnetic separation;(4) sintering pellet technology;

Manganese: mechanical separation (including dressing, screening, gravity separation, strong magnetic separation and flotation), as well as pyrolysis, chemical separation and so on.

Chromium: adopt jigger , shaking table, spiral concentrator, centrifugal concentrator and belt chute separation, but also by hydraulic separation .

Titaniumore, Vanadium ore,magnetite:  a section of grinding, a coarse, a fine and a sweeping magnetic separation process.

Copper: flotation, magnetic separation,gravity separation and other methods or wet smelting, etc.

Lead and zinc:  flotation separation, gravity-flotation and other combined mineral processing methods.

Aluminum: flotation is commonly used.

Nickel :(1) flotation separation ;(2)  crushing, screening and other processes to remove the bulk bedrock with weak differentiation and low nickel content in advance.

Cobalt: flotation separation is commonly used.

Tungsten: tungsten is divided into black tungsten and white tungsten by ore type.The mineral processing methods include manual separation, gravity separation, flotation, magnetic separation and electric separation.

Tin: the mineral processing method is gravity mineral processing and flotation technology.

Molybdenum: mainly flotation separation.

Mercury: there are hand-selected, gravity separation and flotation separation, among which flotation is the most effective and widely used.

Antimony: mainly by hand-selected, gravity separation and flotation separation.

Platinum group :(1) reasonable ball mill, using appropriate cyclone classification;(2) cyanidation and flotation;

Gold: the content of gold in ore is very low. The extraction of gold requires crushing and grinding the ore and separating the gold by mineral processing.Mainly gravity, amalgamation, flotation, cyanide.

Silver :(1) flotation method;(2) single flotation method,the combined process of floating-gravity method and flotation cyanidation method, among which flotation is the most important.

Niobium, tantalum, beryllium lithium: manual separation method, flotation method, chemical or chemical-flotation combined method, Warm cleaning method , radioactive separation method, particle flotation method.

Strontium: the most commonly used method is the flow with jigging and shaking table as the main body.
Rare earth metals: the concentrate containing about 60% rare earth oxides is generally obtained by magnetic separation and flotation separation

Operation of Jaw Crusher

图片
Operation Instructions of Jaw Crusher 1.The preparation before starting: (1) Inspect each bearing to ensure whether it lubricates well, and whether there is enough lubricating grease on the toggle plate joints and bearing inners. (2) Check carefully whether all fasteners are totally fastened. (3) Check whether the drive belt is under good condition, and change the belt if any damages can be found. When there is grease contamination on the belt or bell wheel, it can be clean up with a clean dishcloth. (4) Check whether the protective device is under good condition, if there are any unusual events and safety hazards conditions, should correct them and report. (5) Check whether there are any ore or other impurities inside the crushing cavity. 2.The starting of the crusher (1) After inspecting the machine and transmission parts are under good condition, the machine may starts. (2) This machine can only start under empty load conditions. (3) After having started the machine, shut down the

What factors affect the output of cone crusher

图片
What factors affect the output of cone crusher There are three main factors influencing the productivity of cone crusher : the number of times of the swing of the cone;The length of the parallel crushing area;The size of the engagement Angle.These three aspects directly determine the output of cone crusher. 1.the number of times of the swing of the cone The swing times of the crushed cone is one of the key factors affecting the crusher productivity. Because of the limitation of the meshing Angle of the crushing cavity and the parallel ore discharge area, the crushed ore is discharged along the taper inclined plane mainly by gravity and vibration.When the number of spindle rotation increases, the ore is easy to be discharged, but the number of rotation is too high, which is not conducive to ore discharge, sometimes resulting in faster speed and unable to produce.Therefore, the number of swing of the broken wall has a certain constraint on the improvement of productivity. 2.The l
