Kinetics, as a fundamental requirement of nearly all industrial activities and engineering
researches, plays a great role in leaching processes. Although there are many pieces of …

In a race to save the earth of its rapidly depleting natural resources, the use of Secondary
Raw Materials (SMRs) as alternative replacements in several processes is currently …

Non-sulfide zinc deposits were the prime source for zinc metal production for hundreds of
years. However, during the early 20th century, their significance diminished due to the …

Flotation separation of smithsonite from quartz is difficult due to the dissolved zinc species
activated the quartz flotation. To solve this problem, calcium lignosulphonate (CLS) was …

In order to extract vanadium from LD (Linz–Donawitz) converter slag of steelmaking plant,
an alkaline roasting–acid leaching study was carried out and the effect of different …

A new mathematical model was developed for leaching of zinc ores containing silicates
such as hemimorphite which produce a gel during leaching with sulfuric acid. This model is …

A cleaner method featuring non-salt roasting and ammonium bicarbonate leaching has
been studied for the extraction of vanadium from vanadium slag. Compared to the traditional …

Tailings are remaining processing waste streams from mines, disposed after valuable
minerals extraction from the mined ore. Tailings contain varying concentrations of residual …

This study was performed in two phases of work. In the first stage, alkaline leaching of lead
and zinc from an Iranian low-grade oxide ore was examined and the influence of the …
