The final tailing was rejected in the cobalt-nickel circuit. The flotation pilot plant is shown. Results typical of a single shift during the pilot run are summarized. The recoveries of lead and copper were 87.1% and 81.6% in a concentrate analyzing 20.6% copper, 10.1% lead, 0.99% nickel, and 0.77% cobalt.

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in several processing industries. Historically this was first used in the mining industry. Froth flotation improved the recovery of valuable minerals, such as copper- and lead-bearing minerals. It allows the economic recovery of valuable ...
A. The cost of a Flotation Column can vary widely depending on its size, capabilities, and complexity. Most of the price of Flotation Column ranges from US $ 550 to $ 30000 per Set. It's important to research and compare different models and features to find the best Flotation Column for your needs and budget. Q.
As shown in Figure 3(a), the sulfurization of Cu by sulfur at 850 K (577 °C) produces copper (I) sulfide (Cu 2 S) under low-oxygen partial pressure and copper (II) sulfate (CuSO 4) under high-oxygen partial pressure.During the flotation process, Cu 2 S floats in the flotation solution, whereas CuSO 4 dissolves in the solution. In the latter …
In 1922, cyanide was used to suppress sphalerite and pyrite, and the selective flotation process was developed. In 1925, synthetic flotation reagents represented by xanthate was used, and the reagent dosage was reduced from 1% to 10% of ore amount in bulk-oil flotation to several ten thouhs of ore amount, which made …

Abstract. The challenges in processing nickel laterite ores using flotation process were comprehensively reviewed. Literature shows that flotation has not been …
This size fraction corresponds to a P 80 of about 140 µm which is appropriate for flotation tests. The nickel head grade of samples L, I and S (at the −300 µm size fraction) was found to be 1.2%, 1.1%, and 3.0%, respectively. Nickel was found, more or less, at the same grade in all size fractions in these laterite ore samples.
