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.

Minerals processing is a broad term that includes a number of different processes and is, as a whole, one of the most important aspects of the overall mining operation. Most mined materials, from hard-rock ores to solid-fuel minerals such as coal, oil shale and industrial minerals, are subjected to some sort of size reduction and/or other ...

bioremediation, mineral processing and development, chemical weathering, diagenesis, and concrete degradation. This problem is very difficult because it usually involves multiple scales (microscopic, macroscopic, and field) and multiple processes (advection, diffusion, and chemical reaction) [Lichtner, 1996; Steefel et al., 2005].

In computers, a pipeline is the continuous and somewhat overlapped movement of instruction to the processor or in the arithmetic steps taken by the processor to perform an instruction. Pipelining is the use of a pipeline. Without a pipeline, a computer processor gets the first instruction from memory, performs the operation it calls for, and then goes to get the next instruction from memory ...
