Abstract

This article investigates the chemical INCO SO2/Air process applied for the production of gold from ore, for the environmental impacts of cyanidation wastes causing many problems and for the treatment of cyanide wastes in waste pools. The cyanide leaching process and its environmental effects, which have been widely used in gold production from ore in recent years, have been investigated. Although gold ore is not dissolved in acid and base solutions at room temperature, it is dissolved with very high efficiency of gold ore in aqueous cyanide solution at room temperature. However, the aqueous cyanide solution is very harmful to the environment. Therefore, both cyanide leaching solution and cyanide leaching process waste should not be released directly to the environment. A treatment plant should be established for cyanide solution and cyanide process waste. In this treatment plant, the total cyanide concentration can be reduced to a maximum of 1 ppm. Today, the most common method of treatment for cyanide wastes is the chemical INCO SO2/Air process. Using the INCO Process, the total cyanide concentration in waste is reduced to less than 1 ppm, while toxic cyanides are converted into harmless forms such as ammonium and carbonate.

Siyanür ile cevherden altın üretiminin çevresel etkileri

Abstract

Bu makale, cevherden altın üretiminde, pek çok probleme sebep olan siyanürizasyon atıklarının çevresel etkileri ve atık havuzlarındaki siyanür atıklarının arıtılması için uygulanan kimyasal INCO SO2/Hava prosesi incelenmiştir. Cevherden altın üretiminde son yıllarda yaygın olarak kullanılan siyanür liç prosesi ve çevresel etkileri incelenmiştir. Oda sıcaklığındaki asit ve baz çözeltilerinde altın cevherinin çözünmemesine rağmen oda sıcaklığındaki sulu siyanür çözeltisinde altın cevherinin çok yüksek verim ile çözünmektedir. Ancak, sulu siyanür çözeltisi çevreye çok zararlıdır. Bu nedenle, hem siyanür liç çözeltisi ve hem de siyanür liç proses atıkları çevreye direk verilmemelidir. Siyanür çözeltisi ve siyanür proses atıkları için bir arıtma tesisi kurulmalıdır. INCO Prosesi kullanılarak siyanür atıklarındaki toplam siyanür derişimi 1 ppm altına düşürülebilir. Günümüzde siyanür atıklarının arıtılması için tercih edilen en yaygın yöntem kimyasal INCO SO2/Hava prosesidir. INCO Prosesi kullanılarak, atıklardaki toplam siyanür derişimi 1 ppm’in altına düşürülürken, toksik siyanürler amonyum ve karbonat gibi zararsız formlara dönüştürülmektedir.
