Abstract: The direct reduction of copper sulfide concentrate from Iranian Sarcheshme deposits with carbon in the presence of lime was investigated in the temperature range of 800-1000 ºC. The reduction kinetics was determined by means of weight loss measurements. It was found that the rate of reaction increased considerably with increasing the temperature. The kinetics was also improved whe...

Nowadays, the self-accelerating increase in global temperatures strengthens idea that cutting of CO2 emissions will not be enough to avoid climate change, thus from atmosphere must removed. This gas can easily trapped by converting it bicarbonate using hydroxide solutions. However, converted into a more valuable product make this technology profitable. Several studies show great efficiency when...
