Huntington Mill. The Huntington Roller Mill, here described as a type of the many good roller mills now in use, is best suited for the fine crushing of ores which are not too hard. It consists of an iron pan, at the top of which a ring, B (Fig. 40), is set, and attached to this are three stems, D, each of which has a steel shoe, E, fastened to it.

they were made in a Metzon cutting and polishing machine (Geoform model) and later analyzed in a Leica polarization microscope (DM2500P model). The analysis (Fi g. 2) showed that the ore was composed of a matrix of metamorphic rocks with carbon content (graphitic schist - black slate), quartz and sulfides scattered throughout the matrix (pyrite).

In flotation process, the efficiency and selectivity depend on mineralogy, particle size distribution and liberation, reagents added, mixing, and particle coverage. However, the kinetics of particle recovery is highly dependent on cell hydrodynamic and circuit configuration and operational strategy. Controlling froth depth and gas flow rate, …

An Induced Gas Flotation (IGF) machine is a water treatment device that utilizes the flotation characteristics of air bubbles (Yiantos, 2007 ). The working principle of an IGF is that air bubbles are directly injected into the vessel and forced through a flow passage. Then, the discharged air spreads through the entire IGF vessel via a rotor.

A new boundary condition treatment has been devised for two-phase flow numerical simulations in a self-aerated minerals flotation machine and applied to a Wemco 0.8 m3 pilot cell. Airflow rate is not specified a priori but is predicted by the simulations as well as power consumption. Time-dependent simulations of two-phase …

Pitchblende Uranium Ore. Pitchblende or uraninite, consists mostly of uranium oxides. It is a pitch-black, greenish or brownish black mineral, green or brown when finely powdered; it has a smooth or conchoidal break, and is very heavy. Pitchblende is found in pegmatite dikes, sometimes, as in Cornwall, England, associated with tinstone.

Results show that our flotation machines operate on exceptional grade recovery curves, with respect to coarse and fine particle recovery. The remarkable performance of our machines is related to flotation-favourable hydrodynamics, which produce higher active cell volumes, provide longer residence times, and complement froth removal. ...

The successful operation of a flotation machine hinges around the air and pulp mixture. Maximum results are obtainable when each particle of mineral is brought into direct contact with a bubble of air. This can only be secured by maintaining a thorough mixture of air and pulp during the entire flotation period.

The flotation column was developed for the improved recovery of fine particles too, and is finding commercial application. It embodies principles which are, with modification, appropriate for the flotation of gold from coarse dense sands. A small laboratory column, 1 m high by 50 mm in diameter (Figure 2), was constructed.

Solid density is the mass (g) per unit volume for the material (mm3). The french crushability and french abrasion test gives an abrasivity index and a crushability index that will rate the material in comparison with other materials. The french abrasion test is mainly used to estimate hammer wear life in impactor applications.
