Measurement of acid attack on phosphate rocks

Abstract

A continuous analyser of thermometric type was modified and connected to a batch reactor to obtain quick kinetic curves of phosphate rock acid attack. Different kinds of rocks and two acids were tested in the physical conditions where the dissolution velocity is slow (diluted solutions and low temperatures). A mass transfer model, based on calcium diffusion… (More)
