Mineral,Mineral Processing,Mineral Processing Test

Mineral processing is a process that valuable constituents of an ore are concentrated by means of a physical separation process As one of the initial steps of extractive metallurgy, the main purpose is to prepare the ore prior to downstream purification process The most common mineral processing processes include sample preparation, Comminution,classification and concentration...

Sampling signal processing

In signal processing, sampling is the reduction of a continuous-time signal to a discrete-time signalA common example is the conversion of a sound wave a continuous signal to a sequence of samples a discrete-time signal A sample is a value or set of values at a point in time and/or space A sampler is a subsystem or operation that extracts samples from a continuous signal...
