Chapter 9. Classification
Classification. Classification, as defined by Heiskanen, is a method of separating mixtures of minerals into two or more products on the basis of the velocity with which the particles fall through a fluid medium. The carrying fluid can be a liquid or a gas. In mineral processing, this fluid is usually water, and wet classification is generally ...
Spiral (Concentrators)
For processing of sand minerals normally spirals are being used at onshore where the bottom or base of the plant remain stable and, the heavy minerals (grains with specific gravity generally greater than about 2.9) migrate to the inside of the spiral while the lighter materials (shell, quartz, phosphate, etc.) will be carried in the water stream toward the …

Spiral classifier or hydrocyclone
A friend familiar with this told me the main problem with spiral classifiers is the cut size is directly proportional to retention time (flow rate, Stoke's law, that sort of thing). To get a fine cut size requires flow of almost zero = the finer you want to cut, the lower the flow and density required. Hitzrot, H. W. wrote a great paper in Society for Mining, Metallurgy & …

Spiral Classifier Mineral Processing
The spiral classifier can process the material like gold, sand, etc. Since the specific gravity of solid particles is different, the rate of precipitation in the liquid is different. The spiral classifier is used to treat alluvial sand ore, especially suitable for useful minerals. The monomer has high dissociation and flatness.
