Gold ore gravity separation device

Gold ore gravity separation device
Gold ore gravity separation device type used commonly:
(1) spiral chute;
(2) gold rocking groove;
(3) jigger;
(4) spiral concentrator;
(5) shaking table;
(6) centrifugal concentrator;
(7) dry beneficiation machine.
Various gravity beneficiation equipment its processed materials have a certain size range requirements, above and below this size range, will not get a good sorting.Therefore, before entering the beneficiation process, the materials must be graded.Gravity separation process, commonly used screening grading equipment fixed grizzly, vibrating screen, trommel and curved screen.
Gold ore gravity separation screening process
Greater than the material of 2 mm, mostly using the screening method of grading.Such as sand gold ore before entering the chute beneficiation to use fixed grizzly or vibration sieve to sieve out the more than 15-20mm gravel;With the drum sieve in the gold mining ship to sieve out greater than 10-20mm gravel.
If you need to use a jigger sorting gold ore grinding minerals, vibrating screen to grade mineral particles less than 3-5mm into the jigger, mineral particles larger than 3-5mm Back millmining machine regrinding.
Gold ore gravity separation hydraulic classification machine
Less than 2mm of material grading is generally used hydro-grader.Hydraulic grader beneficiation process follows several forms.
(1) rose water hydraulic grader: This device is divided into the settlement two kinds of free-falling and interference.Before gravity concentration,material is divided into different levels by this type of classifier, in order to facilitate beneficiation.
(2) cone grader: for selected materials into ore and slimes facilitate the beneficiation prior, can also be used for dehydration.
(3) the centrifugal classifier (hydrocyclone): used for fine-level hierarchical or desliming, dehydration.
(4) mechanical grading machines: grinding cycle as a pre-screening or control the grading
