china's zijin plans $1.4 bil share placement to fund copper, gold projects in congo, png. hong kong chinese gold and copper miner zijin mining plans to raise yuan 9 billion $1.4 billion through private share placements in the shanghai stock market to fund buying of assets in congo and papua new guinea and for a mine development project in china, the company said late wednesday.
this is done by contacting the carbon with a solution of sodium cyanide 0.1 to 2% by mass and sodium hydroxide 0.1 to 2% by mass at high temperatures 90 120 c . this results in the reversal of the adsorption process with most of the gold desorbing from the carbon back into solution.

flotation is about creating the proper energy dissipation rate in the cells to obtain optimal contact between the air bubbles and the particles for extracting the minerals. the function of the rotor/stator is to make bubbles from the induced air, suspend the particles, and create an environment for bubbles and particles to make contact and rise to the top as froth for concentration and collection.

some results for floatation and flotation with various related terms are below. m = millions of hits. k = 1000's of hits. e.g. 'australia 420 k / 10.9 m' = 420,000 hits for floatation and australia, 2.29 million hits for australia and flotation. very obviously this method has methodological deficiencies, but it is also demonstrably useful.
this will be very attractive for mineral processing plant customers who rely on forced-air flotation systems. the company plans to offer the new flotation solution globally for both new and existing installations. nextstep is designed to be interchangeable with existing forced-air flotation mechanisms and can be retrofitted into any existing forced-air flotation cell.
