Phosphate rock contained in an acidic slurry is ground by equipment wherein the acidic slurry contacts the metallic surfaces of the equipment. A method for monitoring and controlling grinding ball consumption is provided in which acid-neutralizing particulate iron contained in the acidic slurry is measured and correlated to control curves, which relate particulate iron concentration to slurry

An economical process for treating the acidic pond water to be used in the internal grinding circuit of a wet process phosphoric acid plant. Water is added to a quantity of a hydratable calcium compound, such as quicklime, to form a slaked lime slurry. A sufficient quantity of the slaked lime slurry is reacted with the acidic pond water to obtain a low fluoride solution having a fluoride

melting point of 42.35C. When it is less concentrated, it is a colorlessodorless, viscous liquid with a density of 1.885g/mL. It is non-toxic and non-volatile. The most common phosphoric acid concentration is 85% in water CHEMICAL PROPERTIES It has three acidic and replaceable H atoms. It reacts differently from other mineral acids. Can react with bases to form three classes of salts by the replacement of one, two,or three H atoms. At high temperatures, phosphoric acid

The process for recycling cooling pond water to the ball mill will result in an input of about 1-2% additional P 2 O 5 into the phosphoric acid plant.. EXAMPLE 2. During the month of February, 1982, acidic cooling pond water was treated with slaked lime during four time periods to deterine the corrosive effects on the ball mill (Table II)

Jan 20, 2010 Chemical swelling by phosphoric acid was more favorable than ball mill grinding. However, sequential pretreatment system using ball milling for 2 min and then phosphoric acid swelling for 1 h enhanced the enzyme saccharification rate and the reducing sugar productivity, 84.1% and 28.1 mg/g/h, respectively

Ball mill grinding in dry mode was the most effective method, with the crystal size and the hydrogen-bond network being the two crucial factors in enhancing the reactivity. Remarkably, the yield of 3-acetamido-5-acetylfuran (3A5AF) from chitin dehydration increased to the highest amount (28.5 %) after ball mill grinding (the previous record
