subject: Copper Beneficiation Process [print this page] Copper beneficiation flow Copper beneficiation flow
General beneficiation process: raw coal primary crushing secondary crushing storage bin feeding ball mill gradation flotation re-flotation concentration. Copper concentration generally may use an easy process: once coarse concentration, 2 or 3 occasions fine concentration, a couple of occasions scavenging. Following a portion of ore grinding, the fine ores with 200 mesh fineness is all about 50%-70%. When the copper infect particle dimensions are more fine, a stage of grinding and screening process may be used. In place copper focusing plant, flotation flow is mainly used. Over time of coarse grinding, coarse concentration, scavenging, the coarse concentrate is re-ground and re-selectness to ensure that we are able to get copper concentrate and super concentrate rich in grade. Among this, the coarse ground ores with 200 mesh fineness is all about 45%-50% and also the fine re-ground ores with 200mesh fineness is 90%-95%.

Ore crushing and grinding
In beneficiation plant, the fundamental task of crushing and grinding would be to make selected materials which are disintegrated fully and it has lesser grinding degree for selection work. The grain size the chosen materials ought to be appropriate towards the selected techniques. When the craft and device of crushing work aren't selected properly, or even the production operation management isn't good or even the crushed final production isn't fully disintegrated or perhaps is seriously crushed, technological and economic indications within the whole focusing mill will disappear.
The benefits of the ore crushing process: coarse crushing mill ball mill
The finest feature of mill is big ratio of reduction, which could achieve or exceed the technical needs of total reduction rate in medium or fine two section crushing.
coarse crushing mill ball mill" process flow can replace three sections crushing ball mill" which is development inclination.
Through comprehensive analysis and comparison, this method flow has such advantages:
Production lines are short, less workstage, less publish
Less equipment sets less, less daily maintenance and inexpensive
When crushing tools break lower, ore gemstones whose grain dimensions are under 350 mm may be used and could be directly released to the center of mine, without impacting on the standard delivery of next process.
When the dirt content of selected ore gemstones isn't excessive, after coarse crushing, the crushed ores may come into mill to become next crushed(the dirt content has couple of impact on crushing flow).
Once the ore consists of small objects for example iron, these objects won't modify the normal production procedure for crushing flow.
There doesn't have strict needs for moisture content in ores. Wet mill has less dust and need not be outfitted with dust collector.
7. Preliminary Statistics implies that this method flow doesn't need medium or fine crushing workshop, screening workshop or areas of belt conveyor to ensure that investment could be reduced.
