Diatomaceous earth ore which was designed to remove silt, debris and iron, aluminum and other impurities, so that diatom enrichment. The use of gravity concentration method is generally divided into dry and wet two. Dry-sorting machine is used to get rid of the air separation gangue, or the use of rotary dryers to get rid of organic matter, volatile matter and water, mainly for high-grade ore; wet hydrocyclone separation is used, etc. In addition to out the density of the gangue impurities, mainly for low-grade ore. Diatomite purification methods often use chemical processing, namely the pulp by adding sulfuric acid, hydrochloric acid and auxiliary agents, get rid of iron, aluminum and other impurities. The minerals deserve invest in Kenya are: secondary aluminum, anhydrite, barite, natural carbon dioxide gas, hydraulic cement, diatomite, feldspar, precious and semiprecious gemstones (amethyst, aquamarine, Iolite cordierite, green garnet, ruby, sapphire, and tourmaline), gold, gypsum, kaolin, refined secondary lead, lime, crude steel, coral, granite, marble, industrial sand (glass), shale, and vermiculite. The country also may have produced brick clays, coal, gravel, iron ore, kyanite, meerschaum, mica, murram (laterite), crushed rock, construction sand, and silica sand (from Kaloleni) and so on. The word comminution is not frequently used in the mining industry. Maybe that is because the word is used more frequently in the chemical, ceramics, food, fertilizer, and pharmaceuticals industries. As good an introductory definition that applies to all these industries is that comminution is a process whereby particulate materials are reduced from the coarse feed sizes to the fine product sizes required for downstream or end use. This definition would appear to preclude blasting as part of the mining comminution process. Although I have been at conferences where blasting was said to be the critical first step in mining process optimization. Raw materials will be preheating and pre-decomposition in the cyclone preheater and then carried out into the rotary kiln for clinker burning. After the clinker burning, the temperature starts to fall. Finally with the concrete clinker cooler, the temperature of high-temperature clinker discharged from the rotary kiln will be cooled to the temperature which is suitable to downstream transport, store, and concrete. At the same time, the sensible heat of high-temperature clinker will be recycled, which improves the thermal efficiency and clinker quality of the system. Raw Water is first filtered by filtration unit in series prior feeding R.O.Plant. pressure Sand Filter Unit is provided for removal of suspended matters & turbidity from raw water. PSF Unit is a SS vertical Pressure Vessel. Internally, it is fitted with bottom collecting system. A uniform grades silica quartz sand is charged on the supporting media of pebbles and gravels. This unit is fitted with SS frontal pipe work and Multiport Valve externally. During service cycle water is passed in down ward direction through sand bed, thus entrapping suspended matter & turbid particles. Over a period of time, sand bed gets chocked due to suspended matters resulting higher pressure drop and lesser floe. At this stage filter bed need to be backwashed. Fluctuating commodity prices in today’s volatile economic landscape demand that the mining industry find innovative and sophisticated ways to optimize throughput and reduce costs. Traditional testing methods are time consuming and costly, offering limited testing opportunity and thereby leaving the operation vulnerable to potentially high risks of out-of-spec product and waste from over or under processing.
