The Effect on the Citric Solubility of Langebaan Phosphorite (lanigebaan Phosphate Rock) When Composted with Filter Cake
ثبت نشده
چکیده
Dymond's 1951 compost experiments with filter cake and Langebaan phosphate rock were continued in 1952. Composting increased the citric solubility of the phosphoric oxide in the rock, although not to .the same extent as in the 1951 experiments. Citric solubility decreased with increasing quantities of phosphate rock. Field trials on sugar cane in Natal have been initiated to determine the availability of the phosphoric oxide mixtures of Langebaan phosphate rock and filter cake after composting.

Stabilization of Filter Cake and its Leaching Behaviour: A Case Study with Cementitious and Soluble Phosphate Additives
Filter cake is one of the main waste products of zinc processing industries and it contains a high amount of toxic heavy metals. In this research in order to reduce heavy metals leachability in filter cake, Portland cement, natural pozzolan, diammonium phosphate (DAP), triple superphosphate (TSP), lime, zinc oxide and ground granulated blast furnace slag (GGBFS) have been used. This research’s ...

متن کاملResponse of Sugarcane in a Red Ultisol to Phosphorus Rates, Phosphorus Sources, and Filter Cake
We evaluated the effect of phosphorus application rates from various sources and in the presence or absence of filter cake on soil phosphorus, plant phosphorus, changes in acid phosphatase activity, and sugarcane productivity grown in Eutrophic Red Ultisol. Three P sources were used (triple superphosphate, Araxa rock phosphate, and Bayovar rock phosphate) and four application rates (0, 90, 180,...
متن کاملPhosphate rock formation and marine phosphorus geochemistry: the deep time perspective.
The role that phosphorite formation, the ultimate source rock for fertilizer phosphate reserves, plays in the marine phosphorus (P) cycle has long been debated. A shift has occurred from early models that evoked strikingly different oceanic P cycling during times of widespread phosphorite deposition to current thinking that phosphorite deposits may be lucky survivors of a series of inter-relate...

In the recent decades, water scarcity has become a major challenge for many reasons, especially the inadequate use of water resources. The mineral processing plant is among the most important water-consuming industries. Filtration, as one of the important processes in water recovery, is a process in which the solid-suspended particles are removed from the liquid. In the present work, the effect...
