04.07.2013Flotation (with and without selective flocculation) is thus an established and highly successful commercial process in iron ore industry for removing silica and phosphate impurities. The reduction of alumina containing minerals (kaolinite and gibbsite) by flotation is however not yet investigated adequately and thus remains a challenging problem yet to be solved.

A float process is the most popular method to manufacture flat glass, because the float process ensures high quality and high productivity. In the float process the glass is formed in the float bath, which is a large unit enclosed by refractory-lined steel shell and holds a pool of molten tin. The molten glass is poured on the molten tin, and

Here, we show that the carbon-black-based superhydrophobic gauze was able to float on the surface of water and selectively heat the surface water under irradiation, resulting in an enhanced evaporation rate. The fabrication process of the superhydrophobic black gauze was low-cost, scalable, and easy-to-prepare.

A microorganism, or microbe, is an organism of microscopic size, which may exist in its single-celled form or as a colony of cells.. The possible existence of unseen microbial life was suspected from ancient times, such as in Jain scriptures from sixth century BC India. The scientific study of microorganisms began with their observation under the microscope in the 1670s by Anton van

But we should pay attention to the following points in the flotation: (1) first we should know the type of graphite ore. Graphite ore is divided into crystle graphite ore and earth-like graphite ore. Flake graphite ore is characterized by scaly or leaf-like graphite, ore grade is not high, generally 3% to 5%, the maximum not more than 20% to 25%.

At the heart of the world's glass industry is the float process - invented by Sir Alastair Pilkington in 1952 - which manufactures clear, tinted and coated glass for buildings, and clear and tinted glass for vehicles. The process, originally able to make only 6mm thick glass, now makes it as thin as 0.4 mm and as thick as 25 mm. Molten glass, at approximately 1000C, is poured
