Gravity separation of zinc oxide ore, the method of using grinding machine, spiral classifier, bucket, drum sieve, shaking table for device, the characteristic of zinc oxide ore as raw material, the low grade ore by mechanical method, change the size of the particle size, from the control of particle size, pulp density, shaking bed slope, stroke, speed, make pulp under the impact of the water, the shaking table classification box grading the re-election of methods, such as zinc concentrate.Prominent advantage is the environmental pollution is small, do not need any potions, large quantity, and small investment, good efficiency, waste tailings variable for profit.
The gravity separation method of zinc oxide ore, its characteristic is using the following process steps:
(1) To zinc oxide ore as raw material, with the ore crushing grinding machine(Cone crusher, Jaw crusher, ball mill, etc.) as the ore grain of grain size is less than 100 mm;
(2) After washing, screening, to more than 30 mm of ore crushing into 6-10 of ore grain, after silt can get zinc concentrate;
(3) After sieving particle size is about 1.2 mm of ore grinding machine grinding, spiral separator threshing classification into the table after roughing, zinc concentrate and concentrate;
(4) The table is less than 0.037 mm after roughing time concentrate into table after selection, zinc concentrate and time concentrate;
(5) Once again the first concentrate into table of scavenging, concentrate and tailings.
