Diesel fuel
Petroleum diesel, also called petrodiesel, fossil diesel, or mineral diesel, is the most common type of diesel fuel. It is produced from the fractional distillation of crude oil between 200 and 350 °C (392 and 662 °F) at atmospheric pressure, resulting in a mixture of carbon chains that typically contain between 9 and 25 carbon atoms per molecule. ...
3 Technologies in Exploration, Mining, and Processing
Most applications of flotation of industrial minerals are unique in that a large quantity of the incoming material feed to the plant reports to the froth. The separation process is often complex because the minerals in the ore are very similar in composition and crystal structure, such as halite (NaCl) and sylvite (KCl) (Tippin et al., 1999).

What You Need to Know About Submersible Pumps
Advantages and Disadvantages of Submersible Pumps. The submersible pump offers several major advantages over other types of pumps: Priming: They don't have to be primed. They are self-priming because they operate below the surface of the fluid being pumped. Cavitation: Because they are fully submerged, submersible pumps are not prone to ...
Ores and Minerals
Froth flotation process - This method is based on the difference in the wetting properties of the ore and the gangue particles.The Froth Flotation method is used exclusively for sulfide ores. Leaching Method - The powdered Bauxite ore is treated with mud and a concentrated solution of sodium hydroxide. The ore dissolves in sodium hydroxide to ...
Separation processes
The separation depends on the surface properties of the particles and its preference to attach to the gas bubbles. To meet the necessary requirements of the flotation process, a number of additives can be used to control things like the pH of the liquid-solid mixture, the activity of the solid surface, and the froth that can assist in separation.

Hydrocyclones
Reported values of the air-to-pulp ratio are as high as 16:1. In mechanical cells and flotation columns, the ratio is usually 1:1. As far as contact between particles and bubbles is concerned, the ASH is clearly a very intensive flotation device. However, it is not so effective at handling the froth-phase requirements.

Soil Washing | Geoengineer
Soil washing is an ex-situ remediation technique that removes hazardous contaminants from soil by washing the soil with a liquid (often with a chemical additive), scrubbing the soil, and then separating the clean soils from contaminated soil and washwater (US EPA 1993, 1996). The concept of soil washing is based on the theory that contaminants are prone to bind …
