7 Factors Affecting Froth Flotation Process

· (2) Concentrate grade. The general rule is that the concentrate grade is higher when ore flotation is carried out in a leaner slurry, while the concentrate grade is reduced when it is floated in a thicker slurry. (3) The dosage of the agent. The flotation agent should maintain a certain mass fraction in the pulp to have a good flotation effect.

CANATUAN CU/ZN FLOTATION METALLURGY

low zinc (Zn) ore was fed to the plant. Marketable copper concentrate at 9195% recovery was produced utilizing a highpH bulk sulphide rougher flotation and 2 cleaning stages. Because of increased levels of Zn of the ore body, a Cu/Zn separation circuit was initiated in early 2010 following an intensive laboratory test work program.

MODEL BASED PREDICTIVE CONTROL OF A ROUGHER .

An optimal controller based on dynamic programming was developed in [14], and a hierarchical optimal control strategy was proposed in [17]. Because of the serial structure of the flotation circuit, usually only feed grade, general tailings and concentrate grade are measured online, and the concentrate grade in the intermediate cells remains unknown.

Copper Ore Concentration Optimal Control

Aug 01, A novel ore preconcentration technique using high voltage pulses is proposed in this study. The technique utilises metalliferous graininduced selective breakage, under a controlled pulse energy loading, and sizebased screening to separate the feed ore into body breakage and surface breakage products for splitting of ores by grade.

The copper ions replace zinc atoms on the sphalerite surface creating a pseudocopper mineral surface coverage on the sphalerite which is then collected using copper flotation type collectors. Because most of the iron sulphides also report to the lead flotation tails and so feeds the zinc flotation circuit, typically lime is used to raise pH for iron sulphide depression.
