Embodiment Construction
[0020] The invention is further illustrated by, but not limited to, the following examples.
[0021] Add black drug solution into the container, then add allyl alkylthiocarbamate under stirring, and finally add alkanol, make it mix uniformly, and obtain the product of the present invention.
[0022] Use a ball mill to grind the ore until the fineness of the coarse and fine products is +75μm, accounting for 40% of the mass content, and -38μm, accounting for 90%. Machine re-grinding and re-election, fine particles are separated by stirring flotation machine flotation, one roughing, one sweeping, three beneficiation, respectively output concentrate 2 and tailings.
[0023] In example 1-5, select isobutyl sodium black medicine (A), N-allyl-O-ethyl thiocarbamate (B), n-butanol to make collector flotation certain sulfide ore gold, capture The dosage of the agent is 70g / t, and the agent system is shown in Table 1.
[0024] Table 1: Components and proportioning of collectors of exam...
