Field trials on the store dressing with rock phosphate

An Introduction to the Field Trials Methodology

  The knowledge related to the methodology of the field trial study as a type of intervention studies, yet for many of our researchers is not fully understood. The aim of the current study was a better understanding of conducting this type of research. Field trial studies are done on healthy individuals and aim to prevent. These types of studies such as clinical trials are performed on both i...

Froth 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...

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...
