A method of separating trichomes from cannabis plant flowers that begins with delivering the cannabis plant material to a hopper and continuously moving the cannabis material from the hopper to a porous container in a bath of cold water, at a controllable rate, and moving the cannabis material contained in the porous container, through the cold bath from an entrance end, to an exit end, thereby removing trichomes, which exit the porous container into the cold water. The remaining cannabis plant material is moved out of the exit end of the bath, at substantially the same rate as the cannabis plant material enters the bath. Finally, the water from the bath is substantially continuously filtered thereby separating the trichomes from the cold water.

A multi-zoned paddle screen apparatus 100 is disclosed for separating fiber from a liquid medium during, for example, a grain wet mill or dry grind process. The apparatus includes a housing 106 having first and second zones 108a, 108b situated adjacent one another along a length (L) of the housing 106. First and second screen sections 102a, 102b having a plurality of openings 104 may be situated lengthwise within the housing 106 corresponding with the first and second zones 108a, 108b, respectively. The first and second screen sections 102a, 102b have a circular cross-section, and the second screen section 102b has a larger diameter than the first screen section 102a. An elongated shaft 130 situated lengthwise within the screen sections 102a, 102b includes first and second conveyors 128a, 128b, which correspond with the first and second zones 108a, 108b, respectively, having a plurality of paddles 132. Each conveyor 128a, 128b is configured to move material in a direction along a length of the screen 102a, 102b. There may be more than two zones 108a, 108b.

A classifier and concentrator sluice apparatus with recirculating water in a self contained unit for classifying, concentrating, and washing rocks, minerals, gems, and ore. The unit includes a water reservoir and water circulation system in a drum or a barrel or other container. The barrel includes an open top end and a water circulating pump and water supply lines for circulating water from the reservoir into a basin containing a colander having a selected mesh for separating aggregates by size. The tails including suspended solids and waste aggregate accumulate in the bottom of the tub for disposal.

The present invention includes a mining system adapted to change underwater mining by selecting and harvesting only the target ore or gem. It eliminates costly displacement in mass of ore or material to the surface or shore, reduces pollution of the water column, and minimizes disturbance of the environment. The system includes a trommel fluidly coupled to separators, wherein each separator uses a vortex-like flow pattern to separate high-density sediment from lower density sediment based on flow rate. The present invention is the capable of separating and collecting various sized of desired ore in one pass. Additionally, the system is adapted to be coupled with a ROV dredge to reduce or eliminate diving time and risk of human life.

Aluminum chlorohydrate products include particles of aluminum chlorohydrate, in fractured crystal form, the particles having a basicity in the range of about 50% to about 85.6%, a bulk density of 40 to 65 pounds per cubic foot, and a mean particle size in the range of about 10 microns to about 15 microns. The particles may also have a surface area to weight ratio of about 295 to about 705 m.sup.2/kg, inclusive of both endpoints and all numerical values therebetween, where the ratio is measured by laser diffraction. Methods of producing such products are also disclosed.
