Sieve - Wikipedia

A sieve, fine mesh strainer, or sift, is a device for separating wanted elements from unwanted material or for characterizing the particle size distribution of a sample, using a screen such as a woven mesh or net or perforated sheet material. The word "sift" derives from "sieve". In cooking, a sifter is used to separate and break up clumps in dry ingredients such as flour, as well as to aerate ...

Mining Techniques of the Sierra Nevada and Gold Country

The debris would wash into a series of huge sluice boxes that would catch the gold. The first use of this method is credited to Edward Mattison in 1853. Hydraulic mining was a variation on ground sluicing where the water delivered to the site would be shot through a nozzle at high pressure onto the face of the cliff, thereby washing away tons ...

Particle Analysis in Mining and Minerals

Many of the particles encountered in mining are characterized by sieves (classifiers). Recent advances in computers, cameras, and software make image analysis practical for samples with sizes larger than several microns in diameter. As particle size decreases, sieving and/or dynamic image analysis becomes more arduous or impossible and laser diffraction becomes the technique of choice.
