Practice in testing ores for flotation varies, of course, in its detail, from practice in testing work for other purposes, but in this as in other such work certain general principles apply. These principles would seem to be so obvious that they should not need to be enunciated, but the writer has found in going over the results of ... ="Flotation …
It is obvious that the most suitable treatment for ores carrying gold and silver associated with pyrite and other iron sulphides, arsenopyrite or stibnite, will depend on the type of association. Cyanidation is usually the most suitable process, but it often necessitates grinding ore to a fine size …

In floating copper ores and lead-zinc ores, depression of the iron pyrite is important; but in floating gold-silver ores, the free gold and the iron pyrite are floated. The surface of iron pyrite may be altered while …
The concept of froth crowders and was developed in the early 1950s. The need for crowding froth out of a flotation cell grew along with the size of flotation machines and their cells.. The 1st froth crowder device was patented in 1956 (Fig 1 and Fig 2). What I call the crowder plate is Piece/Item # 12 on the drawings below.

On the basis of pulp routing, a flow-sheet is of the "concentrate-middling" type when the flotation feed pulp passes through a set of machines in series, and these machines deliver finished froth concentrate off the early cells, a clean tailing as the underflow or spigot product of the last cell; and a low-grade froth or middling as the ...
Flotation utilizes the fact that the metalliferous ore particles, and the gangue minerals have different interactions with water. Fundamentally floatation relies on the fact that hydrophobic ore particles and hydrophilic gangue particles can be separated. Hydrophobic means water fearing and hydrophobic substances fundamentally repel water. Hydrophilic means …
