Dolomite is a common rock-forming mineral. It is a calcium magnesium carbonate with a chemical composition of CaMg(CO3)2. It is the primary component of the sedimentary rock known as dolostone and the metamorphic rock known as dolomitic marble. Limestone that contains some dolomite is known as dolomitic limestone. Most rocks that are rich in dolomite were originally deposited as calcium carbonate muds that were postpositionally altered by magnesium rich pore water to form dolomite. Dolomite is also a common mineral in hydrothermal veins. That may have barite, galena, fluorite, etc. Dolomite crystals are colorless, white, buff-colored, pinkish, or bluish. Granular dolomite in rocks tends to be light to dark gray, tan, or white. Dolomite long has been used as a source of calcium and magnesium for animal feeds. It is now available in a number of dosage forms including tablets and chewable wafers, to be taken as dietary supplements. Dolomite is used as a source of magnesia (MgO), a feed additive for livestock, a sintering agent and flux in metal processing, and as an ingredient in the production of glass, bricks, and ceramics. Dolomite is used as a source of magnesium metal and of magnesia (MgO), which is a constituent of refractory bricks. Dolomite serves as the host rock for many lead, zinc, and copper deposits. Dolomite also serves as an oil and gas reservoir rock. This can produce pore spaces in the rock that can be filled with oil or natural gas that migrate in as they are released from other rock units. This makes the dolomite a reservoir rock and a target of oil and gas drilling. Agriculture grade dolomite used for soil neutralization and conditioner to correct acidity. It also finds use as filler in fertilizers. The main ingredient is calcium carbonate, it helps to increase the pH of acidic soils and it provides a good source of calcium for plant. It improves the water penetration for acidic soil.
Urea, also known as carbamide, is a safe, useful compound with a significant history. It is a naturally occurring molecule that is produced by protein metabolism and found abundantly in mammalian urine. he demonstrated that a biomolecule, urea, can be synthesized from a nonbiological starting material. prepared the inorganic compound ammonium cyanate in the lab, then heated it, causing it to isomerize to urea. Now known as the synthesis, the reaction helped to disprove the concept of vitalism, which held that organic molecules can be made only by living organisms.2 In a reaction similar to the synthesis, ammonium carbamate can be converted to urea and water. This is the basis of the process that has been used to produce urea industrially for almost a century. Ammonia and carbon dioxide (CO2) react exothermically to produce the carbamate salt, which is then heated to form urea. The heat produced in the first reaction drives the second. Typically, ammonia and urea are manufactured in the same plant so that some of the carbon dioxide byproduct from ammonia production can be used to make urea. Global urea production capacity is 220 million t/year. Why is urea produced in such large quantities? The answer is that, other than ammonia, urea has the highest nitrogen content of all industrial chemicals and is in high demand as a fertilizer. In the soil, it decomposes back to ammonia (actually ammonium ion) and carbon dioxide. Nitrogen-fixing bacteria oxidize ammonium to nitrate, which is readily taken up by the roots of crops. In addition to its high nitrogen content, urea is particularly useful because it can be applied as a solid in pellet form; and its unusually high solubility in water allows it to be incorporated into solutions with other plant nutrients.
Seed oil or Canola oil is produced using a blend of refined sunflower oil, refined soya oil and refined grape seed oil. Composition: The proportion of each oil used depends on the colour required. Seed oil has a maximum acidity of 0.2º. Available in the following packagings: PET: 1 L bottle 5 L bottle 10 L drum 25 L drum
A combinationof virgin olive oil & refined olive oil, with a pleasant fruity flavour and great aroma. We use fruity and low in acidity extra virgin olive oil to give aroma. The oil is then blended with refined olive oil which softens the flavour and gives colour and clarity. We have 2 versions available: mild & intense. Composition: The percentage used for each type of oil is determined depending on the acidity of each oil to ensure that the end result has a maximum acidity of 0.4º for the mild oil and 1º for the intense blend. Available in the following packaging: MILD: PET: 1 L bottle 2 L bottle 5 L bottle Glass bottle: 500 ml glass bottle 750 ml glass bottle INTENSE: PET: 1 L bottle 5 L bottle
Its high oleic properties are achieved by using sunflower seeds from specific varieties rich in oleic fatty acids. It has a maximum acidity of 0,2º and has a composition which makes it similar to olive oil. Available in the following formats: PET: 5 L bottle 10 L drum 25 L drum
Vegetable oil, to be used mainly for frying. This oil is for the profesional kitchen, no foam or froth is produced, it lasts for longer, gives no smoke and no aromas while frying. this is the, oil highly recommended for frying.
