flotation has now expanded to include oxides, such as hematite and cassiterite, oxidised minerals, such as malachite and cerussite, and non-metallic ores, such as fluorite, phosphates, and fine coal. The flotation method of concentration, used extensively for other metal ores, has only recently been utilized for hematite iron ores.
Batch flotation tests were carried out on samples milled to 80% –75 μm at a slurry density of approximately 30% w/w solids. Synthetic plant water was prepared using distilled water modified by addition of ionic salts to achieve the ionic strength typical of process water at concentrator plants (Wiese, Harris, and Bradshaw, 2005).
The plant works 20 t/h and the balls used in the ball mill is old steel ones. The pulp density at the beginning of the lead flotation line is about 1200 and we decrease it to about 1120 and lower to achieve better recovery.
Froth flotation has been widely used in upgrading iron ores. Iron ore flotation can be performed in two technical routes: direct flotation of iron oxides and reverse flotation of gangue minerals with depression of iron oxides. Nowadays, reverse flotation is the most commonly used route in iron ore flotation. This review is focused on the …

Concentrator Operations. The ores received into the plant, after conventional washing, crushing and grinding, are subjected to differential flotation for the recovery of sulphide copper mineral for smelting and oxide (or non-sulphide) copper minerals for leaching. Sources of feed materials to the concentrator are: (a) Nchanga West orebody.

Mining operations usually provide ore of varying characteristics. At the Donganshan Sintering Plant, the ore is a low-grade, complex, hard-to-separate carbonate containing iron ore, and a two-step flotation circuit was previously developed to overcome the negative impact of the carbonates on the reverse flotation process. However, with …
