The spent liquor is heated through a series of heat exchangers and subsequently cooled in a series of flash tanks. The condensate formed in the heaters is reused in the process, for instance as boiler feed water or for washing bauxite residue. The remaining caustic soda is washed and recycled back into the digestion process.

Chromium processing, preparation of the ore for use in various products. Chromium (Cr) is a brilliant, hard, refractory metal that melts at 1,857 176;C (3,375 176;F) and boils at 2,672 176;C (4,842 176;F). In the pure state it is resistant to ordinary corrosion, resulting in its application as an electroplated

Dewatering is an important process in mineral processing. The purpose of dewatering is to remove water absorbed by the particles which increases the pulp density. This is done for a number of reasons, specifically, to enable ore handling and concentrates to be transported easily, allow further processing to occur and to dispose of the gangue.
165 1996). Corn steep liquor is very high in phosphorus, potassium, and sulfur (Kalscheur, et al., 2008). 166 167 Therefore, the chemical composition of corn steep liquor will probably vary and is reflective of the 168 processing strategy used by a particular manufacturer, depending on which corn component they are 169 interested in isolating.
A plant for ore processing is a series of equipment and devices connected in a constructed way that allow the ore pass through several units, until it get to the concentrate storage. The previous description is general, as some portable simple units of grizzly and a crusher are considered as mineral processing plants. But usually, an ore plant is complicated

The two main methods that exist to create the required pressure differential are Application of vacuum vacuum filtration Application of high pressure to the slurry and squeezing the solids pressure filtration While vacuum filtration is adopted in a large variety of mineral processing industries, pressure filtration would be preferred
Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy. The
The air bubble and mineral particle rise through the pulp to the surface of the froth or foam that is present on the flotation cell. Even though the air bubbles often break at this point, the mineral remains on the surface of the froth. The mineral is physically separated from the remaining pulp material and is removed for further processing.
The programs provide additional control of agglomeration and nucleation mechanisms, which can positively impact final product size control, liquor yield, hydrate classification, and oxalate interference control. Crystal growth modifiers are just one example of Nalco Water's comprehensive portfolio of mineral processing aids.
16 U.S. Environmental Protection Agency, Report to Congress on Special Wastes from Mineral Processing, Volume II, Office of Solid Waste, July 1990, p. 42. 17 Processing of either form of chromic oxide, as well as chromium metal are not primary mineral processing, and are therefore outside the scope of this report. Brief descriptions of these
Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and reseparate them after their division from other earth materials. Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to the
Sep 29, 20030183;32;All of these effects lead to an inadequate extraction of iron species from the alumina liquor and hence poor product quality. During the past three decades, Cytec Industries has pioneered reagent design for mineral beneficiation applications especially in both sulfide and alumina processing
