In general, valuable minerals are denser than barren rocks. We can exploit the different densities of minerals by using the science of gravity separation wherein elements settle at different rates. By suspending crushed ore in a medium like air or water, heavier particles will settle first and lighter ones on top.

A rice milling system can be a simple one or two step process, or a multi stage process. In a one step milling process, husk and bran removal are done in one pass and milled or white rice is produced directly out of paddy.; In a two step process, removing husk and removing bran are done separately, and brown rice is produced as an intermediate product.

Most ores also contain some other non-ore minerals (e.g., hematite) and some other sulphide minerals, especially pyrite (FeS 2). When ore is first processed (typically close to the mine) it is crushed to gravel-sized chunks and then ground to a fine powder and the ore minerals are physically separated from the rest of the rock to make …
