CHARACTERIZATION AND EVALUTION OF REMOVAL CONDITIONS OF LEAD-ZINC-COPPER FLOTATION PLANT WASTE

Abstract

A large amount of mining waste occures due to the intensive mining activities in our country. These wastes may contain different pollutants depending on the type of mining facilities. The lead-zinc-copper flotation waste was investigated in this study contains significantly calcium, iron, magnesium and sulfur elements. The presence of high concentrations of these elements has an environmental problem. For this reason, in this article, firstly, the mine waste was obtained from the Gümüştaş Mining Corporation, the Lead-Zinc-Copper Enhancement Plant. Then, characterization and iron and sulphate removal experiments were investigated under different inorganic acids. Experimental studies showed that about 30% iron and 85% sulphate removal yields were obtained with 4 M HCl concentration.

KURŞUN-ÇİNKO-BAKIR İYİLEŞTİRME TESİSİ ATIĞININ KARAKTERİZASYON VE GİDERİM ŞARTLARININ DEĞERLENDİRİLMESİ

Abstract

Ülkemizde yoğun madencilik çalışmaları neticesinde, fazla miktarda madencilik atığı ortaya çıkmaktadır. Bu atıklar, işletilen maden işletmesinin türüne göre farklı kirleticiler içerebilmektedir. Bu çalışma kapsamında araştırılmış olan kurşun-çinko-bakır flotasyon atığı önemli ölçüde kalsiyum, demir, magnezyum ve sülfür elementlerini içermektedir. Bu elementlerin yüksek konsantrasyonda bulunması çevresel açıdan tehdit oluşturmaktadır. Bu sebeple, bu makalede, Gümüştaş Madencilik İşletmesi, Kurşun-Çinko-Bakır İyileştirme Tesisi’nden temin edilen maden atığının karakterizasyonu neticesinde farklı inorganik asitlerle demir ve sülfat elementlerinin giderimleri değerlendirilmiştir. Deneysel çalışmalar neticesinde 4 M HCl konsantrasyonunda yaklaşık olarak %30 demir, %85 sülfat giderimi elde edilmiştir.
