This 911MPE-PF842 is a complete, but still small miniature froth flotation plant is ideal for in-house pilot plant testing your mining project. Its layout is for a mono-metallic flowsheet (buy section for each additional metal). Its flotation cell agitators tip speed can be varied between 3 set-points. The froth paddles or scrapers also offer 2 rotation settings. As …

The flotation process may be considered an interactive system consisting of many chemical, operational, and equipment variables. Changing any one of these variables causes an overall system response change. This study examines the effects of simultaneously changing the operating variables of: (1) frother concentration and air flow …

The conventional treatment of copper–gold concentrates involves smelting, converting, and electro-refining to produce a copper-cathode product. The conventional treatment of copper–gold concentrates does elicit some compelling reasons to seek an alternative hydrometallurgical process for the recovery of concentrate values.

Magnetic conditioning of flotation feed has been shown to improve the flotation of <38 μm paramagnetic minerals consistent with selectively aggregating these paramagnetic minerals. The process was evaluated using shift composite samples that were analysed for copper and gold.

The gold flotation process is also used to process gold-copper-lead-zinc-sulfur ore; it can effectively identify and extract various gold-bearing sulfide concentrates. The flotation gold recovery plant tailings can be directly discharged, with a high-strength gold flotation machine, which has low costs, and long use life.

This report provides a perspective on the amount of water used by a conventional copper flotation plant, including the makeup water required to compensate for water losses. Much of the global supply of copper originates from mines that also produce byproduct molybdenum, but for simplicity, a single copper concentrate has been modeled for this ...

The presence of gold in porphyry copper ores may require specific flotation strategies to ensure optimum recovery of both Au and Cu, which may differ according to gold mineralogy. Native gold generally floats well with the collectors used for the Cu sulphides (e.g., xanthates, dithiophosphates).

Yes, this is difficult, partly due to the issue of gold being easily floatable and copper eating up a lot of cyanide. For the the simplest way at the process plant level it would generally be a combined flotation, followed by an ammonical (ammonia based) leach of the copper, and then cyanide for the copper, but this is far from easy.

This might be removed by attrition. Depending on the amount and size of this native copper it could be building a circulating load in the milling circuit. This could be recovered by gravity methods from a bleed stream of the cyclone underflow. This has been used to recover native gold in copper flotation operations.

The flotation process is usually configured to maximize copper recovery and, in doing so, a lot of the gold is sent to tailings. The traditional way to recover that would be using cyanide but, due to residual copper present, cyanide consumptions tend to be really high.
