1952 modern, hightonnage mills use the openflow suba rougher flotation machines with suspended mechanisms. 1961 todays demands for sublotation machines keep our modern factory busy. today more sublotation machines are specified than all competitive makes and is the unquestioned first choice in flotation.
The mineral uptake is the natural process in which all the essential minerals enter the plants cellular material, typically following the same pathway as water. the uptake of mineral nutrients occurs at both the roots and the leaves. the process of uptake or transport of mineral nutrients is carried out by the plant cells in two different ways.

In most ores, including iron ore, valuable minerals are usually intergrown with gangue minerals, so the minerals need to be separated in order to be liberated. this screening is an essential step prior to their separation into ore product and waste rock. secondary crushing and screening can result in further classification and grading of iron ore.
Crushing. these drops are subsequently fragmented into smaller ones by acoustic cavitation. the use of ultrasound in emulsification processes is much more efficient than the application of rotor stator systems. physical and chemical effects of cavitation k. s. suslick, university of illinois, usa the energy of the ultrasonic wave is.

For smaller particles, most deposition mechanisms become less efficient, so deposition is less for particles smaller than until it is only about 1015 at about 0.5 m. most of these particles are exhaled again without being deposited. for still smaller particles, diffusion becomes an effective mechanism and deposition probability is higher.
Mechanism having high crushing ability can be employed.echanical crusher machine is used for crushing aluminium cans and punched sheet metal wastes for recycling purpose and also for easy storage and transportation. the crank and slotted lever mechanism converts the rotating motion into reciprocating motion,.
