Mineral processing

Froth flotation is an important concentration process. This process can be used to separate any two different particles and operated by the surface chemistry of the particles. In flotation, bubbles are introduced into a pulp and the bubbles rise through the pulp.

Fluidised bed flotation cell. Historically, mineral ores have been crushed and ground down to a size small enough to undergo froth flotation to separate out the valuable minerals. There is an upper limit on the size of the particles that can be treated so all material to be floated must be ground below this size.

 · 5. Large enrichment ratio, high recovery rate and large processing capacity, especially suitable for processing fine particle size and easy to control and enlarge. Disadvantages The disadvantage of the flotation column is that the particles are difficult to suspend, and the probability of contact between the bubbles and the particles is small.

Aachen reactors form an integral part of the Leachox process for the treatment of gold bearing sulphide flotation concentrates. These flotation concentrates are often refractory to cyanide or require very high reagent additions to achieve even low recoveries as the gold is often locked within pyrite or arsenopyrite.

 · It is worth noting that flotation concentrate recovery decreased sharply but concentrate grade showed no improvement when the percentage of − mm size fraction in flotation feed increased significantly beyond approximately 82%, which is possibly a result of overgrinding that produced particles that are too small to collect by large air bubbles in the mechanical flotation cell.

Most particles are not spherical, but most models are created based on the assumption of spherical particles. Again, in time, accurate, real time particle size analysis will improve our modelling capabilities as well.
