gold mineral flotation normally adopts one stage grinding flotation process but stages grinding and flotation for ore with uneven distribution. grinding fineness of gold for the gold wrapped in sulfide minerals sulfide ore reaches monomer dissociation but for the gold with gangue grinding fineness should reach gold monomer dissociation.

gravity separation is one of the oldest technique in mineral processing but has seen a decline in its use since the introduction of methods like flotation classification magnetic separation and leaching. gravity separation dates back to at least 3000 bc when egyptians used the technique for separation of gold.

the flotation section is composed of two 8 cell sub a flotation machines. the copper section has four rougher cells two scavenger cells and two cleaner cells
the ore pulp slurry is pumped to flotation cells for extracting. the flotation cells are divided into several parts roughing concentration and scavenging (the exact numbers of stages for each part should be decided by test work to reach the best recovery) and with the use of frothing agent and collecting agent the gold concentrate will be collected.

as pyrites. in a typical pyrytic gold ore the gold is encapsulated within an iron sulfide crystal structure. highly oxidized ores generally do not respond well to flotation. advantages of the flotation process are that gold values are generally liberated at a fairly coarse particle size (28 mesh) which means that ore grinding costs are minimized.
13.2.1 ore beneficiation by froth flotation. froth flotation is used to raise the low mineral concentrations in ores to concentrations that can be more economically processed. a concentration of 2530% is suitable for economical smelting of copper.
flotation separation. flotation is the most widely used method for the concentration of fine grained minerals. it takes advantage of the different physicochemical surface properties of mineralsin particular their wettability which can be a natural property or one artificially changed by chemical reagents.
wemco 1+1 flotation cells are commonly used in coarse float applications such as phosphate and potash with feeds of up to 85% plus 65 mesh and maximum particle sizes as large as 10 12 mesh so you can easily treat many particle sizes.
