This paper deals with the application of table flotation to two unusual mineral dressing problems. Both problems involved the removal of interfering minerals at sizes
Absorb. To drink in, suck up, like a sponge. Adsorb. To condense and hold a gas on the surface of a solid, particularly metals. From
The gravity spiral circuit is designed to extract and concentrate “coarse gold’ from the recirculating load in the mill grinding circuit and hence prevent a
The richer the slimes are in gold the easier it is to treat them. In the majority of cyanide plants not enough care is taken
When carrying out experiments on the best methods of cleaning up or obtaining bars of bullion from gold slimes several points have to be considered.
Strong Nitric Acid Many attempts were made to further purify bullion slimes before smelting. The impurities present, as well as the gold, are in a
Comparatively little trouble was experienced in gold milling with regard to the preparation of a pure bullion until the advent of the cyanide process. When
The method just described aims at leaving gold in an insoluble state at the anode. Other impurities are usually left there, and the gold sponge,
