39- liters laboratory flotation machine is applied in ore dressing by the method of laboratory floating. It is concatenation floatation machine with several sets of machines. And the number of chutes is even from 1 to 10. It is left-type or right-type according to user's demand.
Structure and features:
Laboratory flotation machine with 39 liters is impeller mechanical flotation machine. It is composed by the following main parts:
(1). Tank
The tank 1 is welded with steel plate, using the impeller to stir, simultaneously inflating the air into pulp.
In order to adjust the thickness of slurry surface in tank and foam layer scraped, the intermediate tank 15 is made up of two slot panels, in which is the pulp surface regulator 5 installed, orifice 17 is installed on the tank cover 14, which is used to prevent the chaotic movement of pulp affects on the bubble zone, the gangue is entrained mechanically to the concentrate.
Basin liner 6 is equipped in the tank to prevent the tank bottom worn, basin liner can be replaced. Discharging port 8 is placed outside the tank bottom, which is used to storage water when cleaning.
The pulp flows into the intermediate tank 15 and the end tank 3 from the overflow port on the panel, the catheters of the intermediate tank bottom and the cover 14 on the groove wall bottom are put into the next tank, which will flow continuously through all the tanks of flotation machine. The pulp is fed from the feed chute 3, is discharged from the discharging port 8 of the tailing 1, the feed port 16 is equipped in front and at the back of tank bottom, which is easy to change the technological process.
(2)Impeller system
Impeller system is installed in the center of the flotation tank, the vertical arrangement coiled impeller 9 which leaves are up is fixed at the bottom of the impeller shaft 10 and around the vertical shaft tube 12. The tube top is located over the pulp stone and foam layer, the tube bottom is bearing the cover 14. When the impeller rotates, the quantities of air can be absorbed along the vertical tube 12. The protective plate 4 is fixed under the cover 14, the gap between the protective plate and impeller is related to the aeration rate, its maximum gap is less than 3mm, if the gap is too large, it is necessary to replace the protective plate or be adjusted appropriately.
The hole of vertical tube 12 is used to cycle pulp, and make the pulp and air mix well. The upper of the impeller shaft rotates in the rolling shaft 11 installed in the bearing shell, the bearing shell is installed on the beam 7.

Gold Centrifugal Concentrator is a new type of gravity mineral processing device., It can be used not only for placer gold mining, but also for hard rock mining to recover the natural gold, but also used to recover gold from the old tailings. It is widely applied on recovering free gold in all particle size ranges, especially for recovery of fine gold which is lost during the operation of the gravitational concentrators (sluice boxes and jigs).
Test showed that the machine is very effective for separating monomer gold in vein gold deposits as replacement of mercury plate. the recovery can be as high as 99%, The cleaning up cycle is 1~4 hours, and the upgrade ratio is up to 1,000 times. Especially for the case in recovering the natural gold in lode ore with 65% of the ore having a milling size of ¡ª0. 074mm, the recovery for the natural gold is expected up to 98%. For those natural gold of 0.004mm in particle size, the recovery is 97%
The gold centrifugal concentrator can treat particle sizes from below 10 microns up to a maximum of 6mm and is most commonly used for recovery in Gold and Platinum. Other recovery uses include Mercury, Palladium, Tantalum, Copper, Silver and Diamond Indicator Minerals.
Structure and Working Principle
The machine is operated by motor via belt driving draft to make liner rotate at a high speed. Slurries are delivered to liner through feed pipe and are subject to stronger process of separation under the action of centrifugal force. Heavy mineral remains in the lattice chute of liner and light mineral is drained via tailing chute. Concentrate is discharged through outlet after one shift operation and shutdown of the machine.

Jig is one of the relative new methods for gravity concentration. As a rougher or cleaner device, it is widely applied on the separation of gold, tin, tungsten, titanium, hematite, coal and other minerals due to its high processing capacity, large range of separation size and simplicity of operation and maintenance.
Sawtooth wave jig is a new type of jigs,It is one of the types of modern gravity separation equipment. New it has formed series whose use is expanded. Such type of jig uses electromagnetic stepless speed regulation which features even rotation, smooth ore current, strong adaptability to selected materials, good separation effects of medium and fine grains, and water saving.
Sawtooth wave jig is a energy-saving gravity concentration device which is based on the traditional jig according to the distribution rule of jigging bed theory, its jig pulse curve likes the saw-tooth waveform which makes the upward flow faster than the downward; the upward flow time is short, the downward is long, which overcomes the shortcoming of upward flow, downward flow and action time produced by the sine-wave pulse curve, enhances the loose degree of the bed and alleviates the inhalation effects, then the heavy mineral particles in the ore are fully settlement, which enhances the sorting ratio and recovery of equipment. Compared with the sine-wave jig, the recovery of Sn increases 3.01%, W: 5.5%, Pb: 1.63%, Zn: 2.04%, respectively; water consumption is reduced by 30%-40%, site area is decreased 1/3, the stroke can be adjusted, dragging by the electromagnetic adjustable speed motor makes the pumping speed can be adjusted endlessly. Its performance reaches the domestic advanced level, it is one of the ideal energy-saving gravity concentration equipments.
