Description
Technical field
The present invention relates to agent and floatation process are selected in a kind of flotation of big scale Scaly graphite ore deposit soon, belong to graphite flotation technology
Field.
Background technology
China's graphite resource enriches, and reserves and yield all occupy first place in the world.Graphite ore can be divided into crystalloid stone by crystal habit
Ink and aphanitic graphite, and Scaly graphite is divided into two kinds of compact crystal shape graphite and crystalline flake graphite.Compact crystal shape graphite ore
Stone content in nature is less, exploitation it is few, and its grade is high, typically just directly can utilize through picking.
And crystalline flake graphite is the more Scaly graphite of beneficiation research.Crystalline flake graphite is typically due to crystallization preferably, natural floatability, because
This takes traditional floatation process to can be obtained by higher grade and the rate of recovery.But the size due to crystalline flake graphite piece and its property
Can be in close relations, the bigger graphite quality of scale is better.Therefore in order to improve the economic benefit of crystalline flake graphite ore deposit, preferably develop
Using the graphite resource of China, just graphite flakes must be protected in graphite ore dressing process, and ensure grade and return
Yield.
Many experts and scholars had carried out some researchs in terms of graphite ore grinding attachment and multistage grinding etc. in the past, achieved
Some achievements.But low due to there is device efficiency, beneficiation cost is high, the problems such as index is unstable, it is difficult to popularization and application.Document
《The research of protection flaky graphite ore dressing》Disclose and can realize protecting the purpose of flaky graphite using barrel medium ore grinding.
Document《Graphite ore dressing and crystal protection test research》Disclose different Regrinding equipments, grinding media and medium different ratio pair again
The impact of protection graphite crystal, it is believed that desk-top vibromill is used as coarse concentrate regrinding equipment, then grinding media is that steel ball and post mixing are matched somebody with somebody
Than efficiency of regrinding can be improved, can be with effective protection graphite flakes.
The content of the invention
The present invention is for protecting the deficiency for existing to graphite flakes during graphite mineral processing, there is provided a kind of big scale is brilliant

The acetone of methyl alcohol, the petroleum ether of 20～30wt% and 10～25wt%；
2) by step 1) in gained rough concentrate input flotation device in carry out repeatedly selecting selected soon, be obtained graphite concentrate with
Ore deposit, the chats of repeatedly selected rear gained is merged；
3) by step 2) obtained by mine tailing adjust pH value, the kerosene and foaming agent terpenic oil for being added thereto to emulsifier stirs
Mix rear flotation and rough concentrate and mine tailing be obtained, rough concentrate is regrinded through ball milling, add in product of regrinding emulsifier kerosene and
Flotation is carried out after foaming agent terpenic oil primary cleaning concentrate and chats is obtained, primary cleaning concentrate is regrinded through sand milling, product of regrinding
Flotation is carried out after the kerosene and foaming agent terpenic oil that add emulsifier in product again and is obtained recleaning concentrate and chats, two
Secondary selected concentrate and step 2) in gained chats merges after Jing after multiple sand milling and flotation graphite concentrate and chats, will repeatedly
After selected, the chats of gained merges；
4) step 3) in gained mine tailing in add emulsifier after kerosene and foaming agent terpenic oil scanned, in obtaining
Ore deposit and mine tailing；
5) by step 3), 4) in gained chats merge, concentration, ball milling, be added thereto to emulsifier kerosene and
Scanned after foaming agent terpenic oil, regrind Jing many times, after flotation graphite concentrate and tailings.
The beneficial effect of floatation process that the present invention is provided is：
The technique of the present invention realizes the purpose that graphite flakes are protected in ore dressing process, it is ensured that big scale crystalloid stone
The grade and the rate of recovery of black ore deposit concentrate, while beneficiation reagent consumption can be reduced, stable technical process does not increase production cost,
The level of profitability can also be effectively improved.
On the basis of above-mentioned technical proposal, the present invention can also do following improvement.
Further, step 3), 4) and 5) described in emulsifying agent include following component：60～75wt% dodecyl sulphates
Sodium, 25～40wt% sulphation monoglycerides.
It is the dispersibility that improve kerosene in ore pulp using the beneficial effect of above-mentioned further technical scheme, so as to
Grade and the rate of recovery that graphite selects step concentrate slowly can be effectively ensured, and the consumption of floating agent can be reduced.
Further, step 3) in time for regrinding of sand mill be no less than 20min.
It is to be conducive to improving selected operating efficiency using the beneficial effect of above-mentioned further technical scheme, shortens selected stream
Journey, so as to simplify mineral processing circuit.
