Passive lowe coatings function best when on the third or fourth surface (furthest away from the sun), while solar control lowe coatings function best when on the lite closest to the sun, typically the second surface. Lowe Coating Performance Measures. Lowe coatings are applied to the various surfaces of insulating glass units.
Cast Iron Standards. The endproducts to which these materials are produced from include valves, flanges, pipe fittings, plumbing systems, sanitary pipes, and pressure vessels. These ferroalloy and casting standards are helpful in guiding metallurgical laboratories and refineries, product manufacturers, and other endusers...
Taconite. Taconite is a lowgrade iron ore. When the highgrade natural iron ore was plentiful, taconite was considered a waste rock and not used. But as the supply of highgrade natural ore decreased, industry began to view taconite as a resource. Dr. Davis of the University of Minnesota, along with other scientists and engineers,...

Food equipment should be designed and fabricated in such a way that all food contact surfaces are free of sharp corners and crevices. All mating surfaces must also be continuous (, substantially flush). Construction of all food handling or processing equipment should allow for easy disassembly for cleaning and inspection.
produce Portland cement in a second calcination step. Processing about 4– tonnes of nepheline ore yields 1 tonne of alumina, 9–11 tonnes of cement, – tonnes of soda ash, and – tonnes of potash. According to the grade of the bauxite ore, 2–3 tonnes of ore yield one tonne of alumina and about one tonne of red mud (dry weight).

Food Processing has identified five cuttingedge technologies that all use energy such as heat, electricity, pressure and vacuum, singly or in combination, in novel ways to process food better. They kill microorganisms, drive out moisture and perform other functions to preserve food, to make it. Full Story
The recovery yield and the purity of the zinc concentrate produced are lower than the yield and the purity of the zinc oxide obtained with a thermic process. The floatation recovery yield is of the order of 85% compared with 95% for a thermic process.
After beneficiation iron ore availability can improve by about 50%. Steel community and the country demand technological solutions for utilising low grade ores. The technology task that would be imperative: 1. Utilisation of low grade iron ores after beneficiation. 2. Reduction in slime loss by recovery of iron values from slimes. 3.
