Important effects of calcium and magnesium in Aquaculture
Several other effects of calcium and magnesium deserve mention. In ponds, calcium functions to minimize the rise in pH that can occur when photosynthesis rates are high. After plants deplete the water of free carbon dioxide, they can use bicarbonate as a carbon source. But when using bicarbonate, plants release carbonate that hydrolyses and causes pH to increase. Calcium ions react at elevated pH to precipitate carbonate ions as calcium...

Calcium and magnesium use in aquaculture
Hatcheries, farms should monitor levels of essential nutrients Aquatic animals can get the essential nutrients calcium and magnesium from both culture water and their food. Concentrations of calcium and magnesium are seldom measured in waters for aquaculture, but total hardness is determined rather often. Hardness is the concentration of divalent cations — mostly calcium and magnesium — in water expressed in milligrams per liter (parts per million) of equivalent calcium carbonate. Hardness sometimes...

Green Minerals Products for Paint and Coatings
Our lives are touched daily by countless products made with some kind of paint or coating. These products are on the walls of our houses, on the surfaces of appliances and furniture, on our children’s bikes and wagons, on the cars we drive to work, the bridges we drive over, the ships that may have brought us those cars in the first place, on the file cabinets in our offices,...

Ground Calcium Carbonate CaCO3 in Plastics Compounding
Ground calcium carbonate (CaCO3) is one of the most popular mineral fillers used in the plastics industry. It is widely available around the world, easy to grind or reduce to a specific particle size, compatible with a wide range of polymer resins and economical. As an additive in plastic compounds, CaCO3 helps decrease surface energy and provides opacity and surface gloss, which improves surface finish. In addition, when the particle...
