CALCIUM NITRATE - A PRODUCT RESULTING FROM SULPHUR ORE PROCESSING WASTES UTILIZATION

Calcium nitrate is produced in two forms:
- an efficient plant feeder ( 50% solution ;
- granulated organomineral fertilizer containing microelements.
Taking into account the level of paying capacity of agricultural farms on the one hand and limestone wastes accumulated in the process of long-term exploitation of sulphur deposits at Rozdil and Yavoriv SMChPs "Sirka" on the other organization of calcium nitrate manufacture seems reasonable and rather possible. Calcium sulphate , as it is known, is more preferable when compared with ammonium nitrate as far as production and application safety and agricultural efficiency is concerned.
It can be applied to any soils irrespective of their acidity and never acidifies the soil even in case of heavy and annual application. It promotes harmonious plant development and not of its surface part only.
Preparative form (50% solution) being offered is handy and efficient for prompt fertilization of plants , provides for high assimilation of nutrients at minimal outflow into environment. This fertilizer contains calcium in a completely dissolved state and the granulated one a number of microelements ( magnesium, boron, sulphur, humates and others depending on peat deposit) in addition.
Calcium nitrate production process is environmentally safe and efficient. It is based on utilization of limestone wastes and raw-ground limestone , sulphur ore floatation tails in particular. Gas emission in the process of interaction between acid and limestone is neutralized by lime milk which is used for preparing working acid solution.
