like most concentrating devices that utilize physical separation principles the spiral works best on a closely sized feed though in select cases the unit has some tolerance for wide size ranges. in general a coarse size limit would be about 1 mm 20 mesh and a fine limit of approximately 45µm 325 mesh.

mining physical testing.heavy liquid separation hls the separation of mineral sands exploits the natural physical properties of the various mineral types which behave differently under various conditions. we are experienced in several types of heavy liquid separation and use the method best suited to your sample.
physical separation techniques introduction when two or more substances that do not react chemically are blended together the result is a mixture in which each component retains its individual identity and properties. the separation of the components of a mixture is a problem frequently encountered in chemistry.
thereafter the ore is physically separated from any unwanted impurity depending on the form of occurrence and or further process involved. separation processes take advantage of physical properties of the materials. these physical properties can include density particle size and shape electrical and magnetic properties and surface properties.
saskatchewans mineral resources lesson: physical separation of minerals overview students design a process to separate the four components of a mixture containing iron filings salt sand and sawdust. source: this lesson has been adapted for saskatchewan. the original lesson is from the edgeo publication bringing earth science to life.

ii. magnetic separation magnetic separation of mineral particles depends on the magnetic susceptibility of the minerals to be separated. this is a complex phenomenon which is a function of chemical composition especially minor amounts of iron or manganese and atomiclattice structure. the simplest form of magnetic separation is by hand
the froth resembles soap suds and provides the physical separation between the minerals floated and the pulp containing the waste. the froth must be strong enough to support the weight of the mineral floated and yet not be tenacious and nonflowing. it should have the tendency to break down when removed from the flotation cell.
froth flotation / separation flotation: froth flotation is a separation process ore from mineral impurities by way of float ore to the surface through binding to the froth. gravity separation / gravity separation concentration / separation by gravity methods

in broader terms mineral processing consists of two functions. firstly it involves the preparation and liberation of the valuable minerals from waste minerals and secondly the separation these values into two or more products called concentrates.
explain that humans mine mineral resources to manufacture items we use every day. the extraction process requires the separation of the unwanted minerals that make up the rock to get to the good stuff we do want! there are several physical and chemical separation techniques that are used to separate materials from earth.
some minerals require a physical and/or chemical process to remove them from the ore. large rocks containing minerals need to be crushed and milled. the valuable minerals are then separated from the rock using a variety of physical and chemical separation methods.
