Conclusions

  1. 1.

    It has been found that copper sulfate is not an activator of sulfides in the case examined in this paper. This is evidently due to the fact that a very slight concentration of copper sulfare, which induces activation, is present in the tin concentrate itself, so that addition of copper sulfate leads to an excess concentration of copper ions, thus depressing the sulfide minerals.

  2. 2.

    Water glass does not reduce the tin content of sulfides, extraction of the latter into the froth product being greatly reduced.

  3. 3.

    Small amounts of Na2S (50 g/ton) depress sulfide minerals.
