Problems solved by technology

The selectivity of Z-200 is strong, and its ability to collect pyrite is weak, but its ability to collect copper sulfide minerals is weaker than that of butyl xanthate and butyl ammonium black drug
Using single butyl xanthate or butyl ammonium black drug as collector, the flotation recovery rate of copper is higher, but the copper grade of copper concentrate is lower
Using a single Z-200 as collector, the copper grade of copper concentrate is higher, but the copper recovery rate is not high
If a segmented and differentiated medication plan is adopted, Z-200 is used as the collector in the roughing and refining process, an

Example Embodiment

[0013] Example 1

[0014] The technical solution adopted in this embodiment is: the copper grade of the copper ore used in the embodiment and the comparative example is 0.40%, and the grinding fineness is -0.074mm accounting for 60%. The flotation process adopts two stages of roughing, two stages of selection and Two stages of scanning, see the detailed process figure 2 . In order to better compare the flotation indexes, the flotation indexes of each embodiment and comparative example are summarized in figure 1 in.

[0015] The content of Xanthate diester of collector PJ is 60%, the content of Butylammonium Black Pill is 36%, the content of modifier is 4%, and the molecular formula of Xanthate diester is C 2 H 5 -OCSS-C 2 H 4 -COOC 2 H 5 , The regulator is pinitol oil. The amount of collector is 30g / t, the amount of lime is 1000g / t, and the amount of terpineol is 3g / t.

Example Embodiment

[0016] Example 2

[0017] The difference between this embodiment and Example 1 is that the content of the xanthate diester of the collector PJ is 70%, the content of butylammonium black medicine is 27%, the content of the modifier is 3%, and the molecular formula of the xanthate diester is C 3 H 7 -OCSS-C 3 H 6 -COOC 2 H 5 , The regulator is MIBC. The amount of collector is 30g / t, the amount of lime is 1000g / t, and the amount of terpineol is 2.5g / t. The other composition and process flow are the same as in Example 1.

Example Embodiment

[0018] Example 3

[0019] The difference between this embodiment and Example 1 is: the content of the xanthate diester of the collector PJ is 80%, the content of butylammonium black medicine is 18%, the content of the modifier is 2%, and the molecular formula of the xanthate diester is C 3 H 7 -OCSS-C 2 H 4 -COOCH 3 , The regulator is pinitol oil. The amount of collector is 28g / t, the amount of lime is 1000g / t, and the amount of terpineol is 2.5g / t. The other composition and process flow are the same as in Example 1.

Abstract

The invention relates to the technical field of copper sulfide ore flotation, in particular to a copper sulfide ore flotation collecting agent. The copper sulfide ore flotation collecting agent comprises, by mass, 60%-90% of xanthate diester, 10%-40% of butyl ammonium black medicine, and 0%-5% of adjusting agent. The xanthate diester is provided with a certain grade. After the technical scheme isadopted, the copper sulfide ore flotation collecting agent has the beneficial effects of being high in collecting performance and selectivity; single collecting agent PJ is adopted by rough selection,fine selection and scavenging, the copper concentrate with high copper recovery rate and higher copper grade can be obtained simultaneously; the flotation process is not affected by the recycling ofthe production water return, the production index is stable, and the process control is simple; and the price is low, the usage amount of the collecting agent, lime and foaming agent can be greatly reduced, and the production cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of copper sulfide ore flotation, in particular to a collector for copper sulfide ore flotation. Background technique [0002] There are many kinds of copper sulfide collectors, including xanthate, black medicine, mercaptan, sulfur nitrogen and thiourea. Commonly used copper sulfide collectors include butyl xanthate, butyl ammonium black drug, Z-200 (O-isopropyl-N-ethylthiocarbamate), etc. The collection ability of butyl xanthate is strong, but the selectivity is poor, and its ability to collect pyrite is also strong. The collection ability of butyl ammonium black drug is also strong, and the selectivity is slightly better than butyl xanthate. The selectivity of Z-200 is strong, and the ability to collect pyrite is weak, but the ability to collect copper sulfide minerals is weaker than that of butyl xanthate and butyl ammonium black drug. Using single butyl xanthate or butyl ammonium black drug as collecto...
