Selected two Tailings Slurry returns to selected to be selected again and again；Selected two concentrate is final concentrate.
5.1 concentration
Final concentrate slurry carries out concentration technology processing, and thickener underflow high concentration concentrate slurry and overflow water, overflow are obtained after concentration
Water returns to floatation operation and used again.High concentration concentrate slurry enters press filtration operation.
5.2 press filtration
Filter-pressing process processing is carried out to thickener underflow high concentration concentrate slurry, Gold Concentrate under Normal Pressure and filtrate are separated after press filtration, filtrate returns
Floatation operation is used again, and Gold Concentrate under Normal Pressure is final products export trade.
Ore pulp is by above-mentioned flow, and coarse fraction is in the majority in the Gold Concentrate under Normal Pressure of flotation device output, and it is fine that fine fraction is particularly -10um
Grain gold is less, it is impossible to which effectively recovery is lost in mine tailing；Therefore how to overcome existing subparticle loss problem, need a kind of new
Technological process it is existing to solve the problems, such as.
The content of the invention
The purpose of the present invention can be adopted the following technical scheme that to realize：
A kind of post machine combines two close cycles silt particle floatation process, carries out a thick pre-selection, one respectively with two short flotation columns first

One thick three is carried out with flotation device again and sweep two selected operations recovery coarse fraction gold minerals, form coarse fraction（Sand）Flotation, i.e., second
Closed cycle, two class concentrate products merge obtains final finished after dehydration；Flotation process is as follows：
1. stirring
Crude ore pulp（Concentration 32%, fineness -0.074mm 63%）Process is stirred into mixer；
2. flotation column one slightly preselects
One thick pre-selection is carried out with a short flotation column to the ore pulp after stirring and obtains a rough concentrate and a thick mine tailing.
2.1 flotation columns are selected
One rough concentrate is selected into selected post, obtains the selected concentrate of post and post cleaner tailings, post cleaner tailings returns to flotation column
One thick pre-selection is selected again, and the selected concentrate of post enters concentration operation.
3. two roughings
One thick preliminary rejection slurry enters two roughings and carries out secondary roughing, and two rough concentrates and two thick Tailings Slurries are obtained after secondary roughing；
Two rougher tailings return to flotation column one, and slightly pre-selection is selected again, and two rougher concentrations enter the selected operation of flotation device.
4. scan one
Two thick Tailings Slurries are scanned into progress first time is scanned, and are obtained scanning a concentrate and are scanned a Tailings Slurry, scan an essence
Ore deposit returns to two roughings and selected again；Scan mine tailing entrance and scan two operations.
4.1 scan two
Scan a Tailings Slurry and enter and scan two and scanned for the second time, obtain scanning two concentrate and scan two Tailings Slurries, scan two
Concentrate return is scanned one and selected again；Scan the entrance of two mine tailings and scan three operations.
4.2 scan three
Scan two Tailings Slurries and scanned into three progress third time is scanned, obtain scanning three concentrate and scan three Tailings Slurries i.e. most finality
Ore deposit is stored up into Tailings Dam.Scan three concentrate and return and scan two and selected again.
5. selected one
Two rougher concentrations are selected into selected one progress, obtain a selected concentrate and a selected Tailings Slurry, a selected Tailings Slurry returns
Two roughings are returned to select again；It is selected again that a selected concentrate enters selected two.
5.1 selected two
A selected concentrate is selected into selected two progress, obtains selected two concentrate and selected two Tailings Slurry, selected two Tailings Slurry returns
Return and selected select again and again；The selected concentrate of selected two concentrate and post is incorporated as final concentrate and enters concentration operation.
