Stage 2: Float bath Glass from the melter flows gently over a refractory spout on to the mirror-like surface of molten tin, starting at 1,100°C and leaving the float bath as a solid ribbon at 600°C.
R-OH+Au (CN)2-═R-Au (CN)2+OH-. Gold extraction process flow. (1) Adsorption: When the gold-containing cyanide solution passes through the exchange resin column, an ion exchange reaction occurs, and gold is adsorbed on the resin. (2) Desorption: Desorbing the gold on the resin into the solution with a desorbent.
The actual flotation process is a complex, multi-factor coupling separation process. The bubble size is synergistically affected by the frother, collector, slurry properties, mechanical energy input, and air flow rate in the flotation cell. The effect of multi-factor coupling on the bubble size should attract sufficient attention.

Within flow chart (a), the reasons for increased flotation activity of oxyhydryl collectors with (sim C_{12}) are associated with the lack of penetration of reagent molecules into the pores of coal [31, 32]. Within flow chart (b), an increased activity of these collectors is explained on the basis of dependence .
Proceedings of the 8th International Conference on Foundations of Computer-Aided Process Design. Edelmira D. Gálvez, Luis A. Cisternas, in Computer Aided Chemical Engineering, 2014 1 Introduction. Flotation circuits are a common technology for the concentration of a broad range of minerals and wastewater treatments. Froth flotation is …
Flotation is the process of separation of beneficial minerals from a mixture by creating froth on which minerals separate out. This is a method of mineral processing in which different minerals are separated selectively. The ores containing multiple metals, such as lead, copper and zinc, can be selectively extracted by using froth floatation.
particle separation. flotation, in mineral processing, method used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic condition—that is, the surfaces are either repelled or attracted by water. The flotation process was developed on a commercial scale early in the 20th century to remove very fine ...

The slurry flow then enters the feed end of the flotation cells. The slurry at this point is called the HEADS of the circuit. The mineral is then separated and flows over the overflow into a trough called a flotation cell LAUNDERER. The OVERFLOW is now called the flotation CONCENTRATE of the circuit.
