energy saving flotation cell machine

The flow sheet that uses alkaline anioniccationic flotation method treats ore containing feldspar as a major gangue mineral, in which case, acid cationic flotation cannot be used since feldspar also floats in the acid circuit with similar collectors

Illustrative, the flotation process is used for purification of potassium chloride from sodium chloride and clay minerals. The crushed mineral is suspended in brine in the presence of fatty ammonium salts. Because the ammonium group and K+ have very similar ionic radii (ca. 0.135, 0.143nm respectively), the ammonium centers exchange for the surface potassium sites on the particles of KCl, but not on the NaCl particles. The long alkyl chains then confer hydrophobicity, to the particles, which enable them to form foams.[36]

Approximate ball loads can be estimated by assuming 300 lb. per cu. ft. of ball volume and a total load equivalent to 40 to 45 per cent of the mill volume. Rod loads average about 40 per cent of mill volume, and a figure of 400 to 425 lb. per cu. ft. of rod volume should be taken

The effects of the microtubule disrupting drugs (MDD) vinblastine, vincristine and colchicine on a human lymphoma cell line, BM 13674, were investigated. Twelve hours after administration of vinblastine (10(-3) mg/ml), vincristine (10(-2) mg/ml) or colchicine (10(-2) mg/ml), cell death with the characteristic morphology of apoptosis was observed in 71.6%, 82.2% and 76.9% of the cells respectively. The mode of death was confirmed as apoptotic by the occurrence of internucleosomal DNA cleavage, which was demonstrated by agarose gel electrophoresis. For the purpose of casting light on the mechanism involved, inhibition tests were performed on apoptosis induced by one of these drugs, vinblastine, using a phorbol ester (PDBu), zinc sulphate and cycloheximide. PDBu, an activator of protein kinase C, and zinc sulphate, a putative inhibitor of the endonuclease were thought to be responsible for internucleosomal DNA cleavage; both markedly reduced the induction of apoptosis. The protein synthesis inhibitor cycloheximide, on the other hand, had no inhibitory effect. Moreover, cycloheximide treatment per se enhanced apoptosis. This suggests that new protein synthesis is not required for the execution of vinblastine-induced apoptosis. Such a finding is in accord with recent reports suggesting that the "death program" within many cell types may be primed but unable to proceed due to concomitant production of specific "apoptotic inhibitors". It is suggested that phorbol esters prevent vinblastine-induced apoptosis in the BM 13674 cells by activating one or more of these specific "apoptotic inhibitors", possibly by means of PKC-mediated phosphorylation

water was used to pulp the ore. The gold-leaching cell is made of glass, with a capacity of two litres. The tests were performed on a pulp of 50% weight (1000g of ore with 1000ml of solution). Most of the cyanidation tests were carried out with a grind size at 73.9% -74m and 100% passing 149m. Table 1 Analysis of the pyrrhotite-gold ore

One of the better-known theories as to why ovarian cancer develops is that when a woman applies talcum powder to her genital area, particles travel up the fallopian tubes, into the pelvic cavity and then ultimately the ovaries. Once in the ovaries, the particles cause inflammation. This damages the DNA of any surrounding tissue and causes cells to mutate into cancer cells

Cellulose is the main constituent of the structure of plants (natural polymer) that, when extracted, is employed for making paper, plastics, and in many combinations. Cellulose is made up of long-chain molecules in which the complex unit C5H10O6 is repeated as many as 2000 times. It consists of glucose molecules with three hydroxyl groups for each glucose unit
