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 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.
The Mountain Pass Rare Earth Mine and Processing Facility, owned by MP Materials, is an open-pit mine of rare-earth elements on the south flank of the Clark Mountain Range in California, 53 miles (85 km) southwest of Las Vegas, Nevada. In 2020 the mine supplied 15.8% of the world's rare-earth production.
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.

A cleaning company has been fined $171,000 after federal investigators found 11 children working a "dangerous" overnight shift at a meat processing plant in Iowa.
The chloride process became obsolete with the development of the cyanide process. [22] [23] In 1887, John Stewart MacArthur, working in collaboration with brothers Dr Robert and Dr William Forrest for the Tennant Company in Glasgow, Scotland, developed the MacArthur-Forrest Process for the extraction of gold ores. By suspending the crushed ore ...
