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.
This is a list of Superfund sites in Missouri designated under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) environmental law. The CERCLA federal law of 1980 authorized the United States Environmental Protection Agency (EPA) to create a list of polluted locations requiring a long-term response to clean up hazardous material contaminations.

It is also used for production mine planning to optimize the ore feed to the processing plant. There are four important components or steps to developing a geometallurgical program,: [1] the geologically informed selection of a number of ore samples; laboratory-scale test work to determine the ore's response to mineral processing unit operations
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 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.
