The unique features of the DNi Process™ The DNi Process™ uses nitric acid to dissolve and recover any saleable metal found in lateritic ores, tailings and waste material from other processes including, potentially, slag produced by ferro-nickel plants. The unique and patent-protected aspect of the DNi Process™ is that 95% of the nitric acid is recycled (with 5% remaining in a nitrogen ...
process plants that convey metal-bearing slurries through piping, valves, vessels, and other equipment. In order to decrease chemical reaction times and therefore increase throughput, these process plants now regularly operate at elevated temperatures and pressures and must additionally contend with low pH, complex chemical interactions, and both erosion and scaling by solids.

This process of leaching is termed as high-pressure acid-leaching process or HPAL process, which is highly selective to nickel and cobalt. A pressure leaching autoclave is used in this process that receives the hot feed slurry through positive displacement slurry pump and maintains the slurry residence time between one and two hours. Pressure leaching autoclave operates at 6 bar above the ...

nickel. Process gases are cooled, and particulates are then removed by gas-cleaning devices. Nickel Refining Various processes are used to refine nickel matte. Fluid bed roasting and chlorine-hydrogen reduc-tion produce high-grade nickel oxides (more than 95% nickel). Vapor processes such as the carbo-nyl process can be used to produce high-purity nickel pellets. In this process, copper and ...

The nickel process plant was completed in 2016, and shares a number of sections with the Sentinel process circuit. It is designed to produce 38,000 tonnes of nickel in concentrate, but this can be increased to 60,000 tonnes. The plant is integrated with the Sentinel copper circuit so that it can produce additional copper concentrate when not producing nickel. Enterprise and Sentinel are 100 ...

The Hemp, Inc. "industrial hemp processing" (decortication) plant is a line of Temafa automated equipment, designed to separate the fiber from the core of the hemp or kenaf plant through a process known as decortication. It automatically separates the fiber and core from the plant and processes it into material that can be made into other products.
The separation process for nickel is highly dependent upon the type of ore. Nickel sulfides, such as those found in the Canadian Shield and Siberia, are generally found deep underground, making them labor-intensive and expensive to extract. However, the separation process for these ores is much cheaper than for the lateritic variety, such as those found in New Caledonia. Moreover, nickel ...
