Description
Technical field
The present invention relates to a kind of collecting agent for the Oxide Copper Ore Flotation technique containing magnetic impurity.
Background technology
In the copper resource of China, cupric oxide ore accounts for a quarter.Oxidized zone is arranged at most of copper deposit tops, or even has
Formed independent big-and-middle-sized cupric oxide mineral deposit.Therefore, development and utilization cupric oxide ore, the development for China's Copper Processing Industry has
It is significant.
Often clay content is higher for cupric oxide ore, and granularity is thinner, easily causes that chats amount is big, production is unstable in floatation process
It is fixed, the drawback such as big, manufacturing cost height of floating agent consumption, its processing is always one of problem of domestic and international ore dressing field.Greatly
Amount experimental study shows that composition more pure copper oxide mineral is such as：Malachite, chessy copper etc. are floating by simply vulcanizing
Method is selected just to result in the oxidation copper concentrate compared with high-grade and the rate of recovery.But Fe, Ni, Co, Mn magnetic are mixed into by absorption or machinery
Property impurity the floatability of copper oxide mineral be deteriorated, conventional flotation medicament is difficult to effectively reclaim copper mine.
The content of the invention
The present invention is solved, and the refractory copper oxide mineral beneficiation concentrate grade containing magnetic impurity is low, the low skill of the rate of recovery
Art problem.
The technical scheme is that there is provided a kind of collecting agent for the Oxide Copper Ore Flotation technique containing magnetic impurity,
The collecting agent is combined capturing and collecting agent, and the combined capturing and collecting agent is 96~576 parts of penta xanthate and 64~384 parts of 4- by parts by weight
Diphenylamine sulfonic acid sodium salt is constituted.
Further, the weight ratio of penta xanthate and 4- diphenylamine sulfonic acid sodium salts is (1~2) ︰ 1 in the combined capturing and collecting agent.
Further, the weight ratio of penta xanthate and 4- diphenylamine sulfonic acid sodium salts is 3 ︰ 2 in the combined capturing and collecting agent.
The present invention is using preferable, the strong collecting agent of collecting ability of selectivity, difficult choosing oxidation of the open circuit flows containing magnetic impurity
Copper mineral, is obtained refractory copper oxide rough concentrate, then the technique being combined using low intensity magnetic separation-high intensity magnetic separation, magnetic is improved to greatest extent
The grade of choosing oxidation copper concentrate, so as to reach the purpose for improving oxidation Cu Concentrate Grade and the rate of recovery.
The ore-dressing technique for the cupric oxide ore containing magnetic impurity that the present invention is used comprises the following steps：(1) it is raw ore is levigate
55~90% are accounted for -0.074mm；(2) raw ore after levigate is carried out easily selecting cupric oxide roughing, obtains easily selecting cupric oxide roughing smart
Ore deposit and Yi Xuan cupric oxide rougher tailings；(3) easily select the progress of cupric oxide rougher concentration is selected to obtain easily choosing oxidation copper concentrate to described；
Easily select cupric oxide rougher tailings to scan to described, obtain easily selecting cupric oxide to scan mine tailing；(4) easily cupric oxide is selected to sweep to described
Select mine tailing to carry out refractory copper oxide flotation and obtain refractory copper oxide flotation concentrate；The collecting agent that the refractory copper oxide flotation is used
For combined capturing and collecting agent, the combined capturing and collecting agent is made up of penta xanthate with 4- diphenylamine sulfonic acid sodium salts；(5) it is floating to the refractory copper oxide
Concentrate selection carries out low intensity magnetic separation, high-gradient magnetic separation and obtains cupric oxide magnetic concentrate successively；The magnetic field intensity of the low intensity magnetic separation be 0.2~
0.5T；The background magnetic field intensity of high-gradient magnetic separation is 0.7~1.2T.
In ore-dressing technique of the present invention, the easy choosing oxidation copper concentrate of output and the grade of cupric oxide magnetic concentrate are higher, are
Hydrometallurgy provides good raw material.
Collecting agent of the present invention can carry out flotation to the refractory copper oxide ore of the magnetic impurities such as iron content, manganese, difficult
Copper oxide ore is the low cupric oxide ore of copper grade, the mine tailing of the preliminary flotation of such as cupric oxide, low, the traditional collecting of its copper grade
The xanthate of agent penta is difficult the collecting effect played.
In the present invention, added in the cupric oxide ore in combined capturing and collecting agent, combined capturing and collecting agent in addition to penta xanthate, also
Added with a kind of new collecting medicament：4- diphenylamine sulfonic acid sodium salts.It is unshared on nitrogen-atoms on 4- diphenylamine sulfonic acid sodium molecules
Solely to electronics as with for body, there is provided solely to electronics and the Cu on refractory copper ore thing surface2+Cation is shared, with covalent bond form knot
It is combined into more stable chelate；Meanwhile, the sulfonate radical on 4- diphenylamine sulfonic acid sodium molecules can be with copper oxide mineral surface
Cu2+、Fe3+、Ni2+、Co2+、Mn4+Insoluble chemical compound is formed, both modes act on refractory copper oxide mineral surface simultaneously,
Make mineral surfaces are hydrophobic to float.
The advantage of the invention is that：The beneficiation reagent can make some refractory copper oxide mineral be recycled utilization, not only
Be conducive to saving resource, and it is significant for the nervous situation for alleviating Mineral Resources in China.
