plays a major role in the evaluation of new ore bodies, process flowsheet development, plant design, process optimisation and quality control. The metallurgy of iron ore is becoming increasingly complicated. In the evaluation of a new iron ore deposit, it is essential that the chemical composition, physical properties, mineralogy and metallurgical

Figure 1 is a generalized diagram of a conventional copper flotation plant from the point where ore first enters the circuit to the production of concentrate and tailings. To prepare ore for the flotation process, run-of-mine ore, which may contain from about 2 to 5 percent water, by weight, when mined, is

We claim: 1. A process for recovery of iron from iron ore consisting essentially of subjecting the ore to cationic gangue flotation to produce a flotation concentrate as underflow and flotation tailings as overflow, and subsequently scavenging iron from said tailings by means of a wet high-intensity magnetic separator, whereby a magnetic concentrate of increased iron content and a …

Iron Ore Concentration Process Magnetite is mined in large chunks and is crushed into small particles by a series of crushers. After primary crushing with jaw crushers and secondary crushing with gyratory crushers and tertiary crushing with cone or high pressure grinding rolls (HPGR), the ore is screened on vibrating screens to size the particles.

product quality has forced iron ore producers to re-examine their process flow sheets and evaluate alternate or supplemental processing routes. The requirement for higher quality iron ore demands that the silica and alumina contents be lowered for effective use in the steel making. Reverse flotation (silica

Copper concentrators typically treat up to 100 000 t of ore per day. They are located directly at the mines to achieve low transport costs. The copper recovery efficiency is over 90 %. About 95 % of the ore input goes into the tailings, which are stored in large dams near the mine and are used for water recycling to the flotation stages.
