NIAflow is used to design new mineral processing plants as well as optimize existing plants. Applying machine-specific parameters, the software computes the material flow through entire plants and provides product forecasts. Based on these results, process layout and machinery setup can be evaluated. NIAflow is a product of Haver & Boecker.
A process flow diagram (PFD) is a diagram commonly used in chemical and process engineering to indicate the general flow of plant processes and equipment. The PFD displays the relationship between major equipment of a plant facility and does not show minor details such as piping details and designations.
The Argus Cogeneration Plant of Searles Valley Minerals. The Argus Cogeneration Plant is a coal-fired power station located adjacent to the mineral processing plant in Trona, California. The power station has nameplate capacity of 63 MW and produced 296 GWh of electricity in 2018. [11] It is the last coal-fired power station still operating in ...
The Merrill–Crowe Process is a separation technique for removing gold from the solution obtained by the cyanide leaching of gold ores. It is an improvement of the MacArthur-Forrest process, where an additional vacuum is managed to remove air in the solution (invention of Crowe), and zinc dust is used instead of zinc shavings (improvement of Merrill).
The first step in the sequence leading to the construction of a process plant and its use in the manufacture of a product is the conception of a process. The concept is embodied in the form of a "flow sheet". Process design then proceeds on the basis of the flow sheet chosen.
Sepro Mineral Systems Corp. is a Canadian company founded in 1987 and headquartered in British Columbia, Canada.The outcome of the acquisition of Sepro Mineral Processing International by Falcon Concentrators in 2008, [1] the company's key focus is the production of mineral processing equipment for the mining and aggregate industries.

Gold occurs principally as a native metal, i.e., gold itself.Sometimes it is alloyed to a greater or lesser extent with silver, which is called electrum.Native gold can occur as sizeable nuggets, as fine grains or flakes in alluvial deposits, or as grains or microscopic particles (known as colour) embedded in rock minerals.
The heap design usually incorporates collection sumps, which allow the "pregnant" leach solution (i.e. solution with dissolved valuable metals) to be pumped for further processing. An example is gold cyanidation , where pulverized ores are extracted with a solution of sodium cyanide , which, in the presence of air, dissolves the gold, leaving ...
