Flotation machine is the equipment to complete the flotation process, which is also called flotation cell. It is widely used for the rough, fine and reverse flotation operations of copper, lead, zinc, nickel, molybdenum and other non-ferrous metal, ferrous metal and nonmetal minerals.
The roughing-table concentrate carries about 4 1/2 per cent. copper and 38 per cent. iron. Flotation and table concentrate mixed, forming the mill concentrate, assay 9 per cent. copper, 30 per cent. iron and 16 per cent. insoluble. Flotation tailing assays about 0.4 per cent, copper. The recovery by flotation is about 82 per cent.
Flotation Period. The flotation time has a direct impact on the indicator's quality. When the period is too long, the grade of the concentrate falls; when the time is too short, the grade of the tailings rises. As a result, the flotation time necessary for different minerals must be determined through experimentation. The quality of the water

I have been given a project on optimization of copper concentrate grade so as to improve copper and gold recovery. I need help on the main factors which I have to consider in my project. The targeted copper concentrate grade at the plant is 18- 20%Cu, but currently the target is not achieved. The plant ore is chalcopyrite.
This molybdenum flotation circuit, based on 250-500 tons per 24 hours is designed for low-grade molybdenum ore having high-grade streaks and with pyrite-quartz gangue. It is also basically sound for many other friable sulphide ores, such as antimony, silver and even some lead ores. The basic ideas stressed in this moly flotation …
For copper sulfide, and oxide copper ore, our flotation machines assist in efficiently separating copper particles from impurities within liquid mixtures, which helps save time …
The overall results attained with the single stage copper flotation columns are equal to the two stage conventional cleaner circuit in copper recovery. A concentrate grade of 29.83% Cu with a sulfide copper recovery of 90.36 percent for the column flotation cleaner circuit as compared to a 29.99% Cu concentrate grade and a sulfide …
Comparative Study on Prediction Methods of Copper Concentrate Grade for a Copper Flotation Process Abstract. Copper flotation process is a complex industrial process. Concentrate copper grade (CCG) is one of the important production indexes of flotation process, and it is also one of the important factors to determine the economic benefit ...
Question: copper flotation circuit is used to concentrate 100 tonnes/hr of ore, valuable mineral is chalcopyrite containing 34.5% copper (s.8 4.2) with a siliceous gangue (s.8 2.6). The circuit layout is shown below (Fig. B2): Circuit Feed ROUGHERS Final Tailings Dilution Water CLEANERS Final Concentrate Fig. B2 Flotation circuit The following ...
This means that 95.7% of the copper present in the ore was recovered in the concentrate, while the rest was lost in the tailings. (c) The % Cu Loss can be calculated by subtracting the % Cu Recovery from : % Cu Loss = 100 – 95.7 = 4.3% This means that 4.3% of the copper present in the ore was lost in the tailings.

The copper ore flotation method can be divided into forward flotation and reverse flotation according to the separation of valuable components: discharging useless minerals (gangue minerals) in the slurry as tailings are called forward flotation. Otherwise, it is called anti-flotation. Copper is one of the important non-ferrous metals. In the …
You best depress the metal that's the most present, the metal you have the most of & you float the metal you have the least of. In this case, flotation of a small amount of lead from the copper concentrate would maximize copper recovery, while removing enough lead to make the copper concentrate more marketable.
The cell can be modified to handle high density slurries. RCS flotation technology provides excellent air dispersion, producing fine even sized bubbles. Maximum flotation recovery and performance have been achieved by careful attention to the tank design. RCSTM flotation machines are available in sizes 0,8 m3 to 600 m3 DV™ flotation mechanism
