SEPARATION OF VALUES FROM THE EGYPTIAN SAND PLACERS

Abstract

The main aim of this contribution is to study the amenability of concentrating black sand minerals by using froth flotation. Extensivej research program and the flotation behavior of zircon, rutile and i ilmenite has been conducted over wide pH range and using different (various a·eagent schemes). The study is consider an effort tol characterize and to put forward same basic study related to surface! chemistry of froth flotation of zircon and Ti-beaa·ing minerals. First, study the flotation behaviors of a single pure zircon ilmenite and rutile using Hallimond tube. The flotation response of the tluee minerals with diffea·ent anionic, cationic and non ionic collectot· was studied. Different type of inorganic and organic resurfacing agents such as lignin sulfonate, polyoxyethylene glycol and polyvalent ions were 1 employed to enhance the selectivity between zit·con and Ti-bearing/ minea·als (ilmenite and rutile). 1 A further flotation study on synthetic mixtures of pure zircon,) pure ilmenite and pm·e rutile has been carried out. The aim of these experiments is to determine the efficiency of separation of these mineralsJ by flotation independently of the proposed theoretical commentary of: the data obtained, it should be conceived from the experiment data of\ this investigation that lignin sulfonate, sodium oleate, and I or1 polyoxyethylene glycol, sodium oleate reagent system open up new potential fields and challenge
