Three factors were measured in the flotation process of copper ore: the copper grade in a concentrate (β), the copper grade in tailings (ϑ), and the recovery of copper in a concentrate (ε). The experiment was conducted by means of a Jameson cell. The factors influencing the quality of the process were the particle size (d), the flotation …

Sedgman undertook a Concept Study / Scoping study for a 30,000 t/d copper concentrator, and copper flotation plant with the design capability of Mineral processing for 600,000 t/a copper flotation plant processing both oxide and sulphide ores. The plant was designed to treat 385,000 t/a of oxide ore or 600,000 t/a of sulphide ore over a total ...

In flotation of gold-containing base metal ores, a number of modifiers normally used for selective flotation of copper lead, lead zinc and copper lead zinc have a negative effect on the floatability of gold. Such modifiers include ZnSO. 4 ·7H. 2. O, SO. 2,Na. 2. S. 2. O. 5. and cyanide when added in excessive amounts.

In this study, the flotation of oxidized copper ore obtained from Ergani Copper Mining Company in Turkey was performed. This ore contains 2.03% copper, 0.15% cobalt and 3.73% sulfur. An effective ...

In Hanönü copper mine the plant, the ore was ground to below approximately 20 μm and the chalcopyrite was floated in Outotec Floatforce tank cells of 50 m 3 in the rougher flotation circuit and tank cells of 20 m 3 and 10 m 3 in the cleaning circuits. KAX as a collector and OREPREP F-549 as a frother were used in the plant and pH was ...

However, the ability to exploit microwave-induced fracture by improving flotation recovery and grade, and/or increasing the primary grind size to effect liberation has significant potential benefits in terms of increasing plant throughput and metal production while reducing metal specific energy consumption, even without significant …

tion minerals is significant in flotation plants. Our R&D studies have concluded that reducing the particle size of the ground ore to 40 microns will. esult in an increase in recovery and concentrate. Moreover, instead of the existing 4-battery 500 mm hydrocyclone set, a new 8-battery 35.
