Preparation of Phosphate Mine Tailings and Low Grade Rock Phosphate enriched bio-fertilizer
Phosphate tailings pose significant risk to the environment as point sources of basic, carbonate-rich effluents. This waste may be judiciously used for the biofertilizer preparation. The enrichment of compost by adding low grade rock phosphate also offers a potential preposition for the effective utilization of insoluble P. Experimentally, the compostable material (Biogas spent slurry) is mixed...
متن کاملCan Phosphate Salts Recovered from Manure Replace Conventional Phosphate Fertilizer?
Pig farming produces more manure than can reasonably be spread onto surrounding fields, particularly in regions with high livestock densities and limited land availability. Nutrient recycling offers an attractive solution for dealing with manure excesses and is one main objective of the European commission-funded project “BioEcoSIM”. Phosphate salts (“P-Salt”) were recovered from the separated ...
متن کاملFroth flotation of phosphate rock
The development of froth flotation is traced from its earliest-known use through the discoveries leading to the present knowledge of the science. The factors influencing the flotation of non-sulfide and non-metallic minerals are discussed, and the machines used in commercial flotation operations are described. Experimental work on the flotation beneficiation of phosphate rock is presented as an...
متن کاملEnhancing rock phosphate integration rate for fast bio-transformation of cow-dung waste-paper mixtures to organic fertilizer
Rock phosphate (RP) addition in cow-dung waste-paper mixtures at rates above 2% P has been reported to increase the rate of bio-transformation and humification of organic waste mixtures during vermicomposting to produce organic fertilizer for organic farming. However, the optimization of RP for vermicomposting was not established. The objective of this study was to determine the optimal amount ...
متن کاملWeil: Soil–plant Influences on Phosphate Rock Efficacy
of nutrients, especially phosphate rock (PR) in subSahara Africa (McClellan, 1989; Buresh et al., 1997). Affordable technologies are needed to allow smallholder farmers Substantial deposits of PR in many sub-Sahara Afrito effectively use the phosphate rocks (PRs) found in many African countries. A pot study was conducted in Tanzania using two PRs can countries are too low-grade to justify comme...
