Silicon recovery from diamond wire saw silicon powder (DWSSP) waste is of great
significance for increasing production profits and alleviating hazardous effects on the …

The considerable accumulation of phosphogypsum (PG) not only occupies land space but
also causes environmental pollution, leading to threatening human health. Under the …

Recent research on mineral carbonation has focused attention on multi-step processes
which appear more attractive than single-step processes due to the higher purity of the final …

Indirect carbonation is a suitable method for carbon dioxide (CO 2) removal from the
environment, and it requires an acid to dissolve the calcium ions and a base to precipitate …

The structures of phosphate ore particles have great impact on their dissolution behavior. In
this work, two kinds of fluorapatite structures in the phosphate ore matrix were identified. The …

In this paper, we are presenting a two-step biological process to recover phosphorus
solubilizing low-grade phosphate rocks. We start with a “growing” stage, where the biogenic …

Phosphogypsum is a solid byproduct in the production of phosphoric acid in the traditional
sulfuric acid process, and its output has caused a huge economic and environmental …

This article discusses the method of obtaining phosphorus-containing components from
cottrel dust from the industrial wastes of the New-Jambul phosphorus plant. Accumulated …

The dissolution kinetics of the Abu-Tartur phosphate rock using dilute hydrochloric acid has
been investigated. The influence of acid concentration, liquid/solid ratio, particle size and …

The dissolution of aluminum, calcium, and iron from calcined fly ash with hydrochloric acid
was investigated using a batch reactor at temperatures from 315 to 345 K and over the acid …
