The estimation of platinum flotation grade from froth …
applications in automated process control of flotation systems have been reported, particularly in the platinum industry. One of the reasons is that to date froth features could not be related to key performance indicators such as froth grade and recovery. The research focus areas have been the use of froth appearance to detect predefined

The gold would attach itself to a rising air bubble and float. In today's world, the chemistry has improved enough to better promote the coating of the gold with an oil, a stronger bubble froth, while depressing the gangue material. You could probably process a 5 gallon bucket of fines in a cement mixer, with a few teaspoons of pine oil.

Froth Crowder
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.

Artisanal and Small-Scale Gold Mining Without Mercury
Bubbles containing gold and other hydrophilic minerals accumulate at the top of the water level as froth. This froth is then scraped off to create a concentrate of gold and other hydrophilic minerals. Flotation creates high quality concentrates and is good at capturing fine gold. Flotation usually requires a substantial amount of capital ...

The Importance of pH in Flotation
Starch is particularly useful in the flotation of native gold in the presence of flocculent gangue slime ; a small amount of the reagent will generally deflocculate the gangue without affecting the gold. Sodium silicate used for a similar purpose has a strong tendency to depress the gold.
