Environmental Safety Issues and Organomineral Fertilizer Production
The authors show environmental safety capability using waste of bio-chemical, hydrolysis and mining-and-processing plants in deep concentration of phosphorites. The article offers methods for manufacturing organomineral fertilizers from lignine and phosphorite; oxidized coal and phosphorite (apatite concentrate); and lignine, oxidized coal and phosphorite. The developed organomineral fertilizer production technology enables enhancement of grain harvest by 62% with rock phosphate meal and by 95% with superphosphate.
