Abstract

Bu çalışma kapsamında bir triboelektrik ayrım düzeneği tasarımı ve bu düzeneğin ülkemizdeki
belli başlı kömür cevherlerinin ince boyda zenginleştirilmesinde kullanımı incelenmiştir. Deneysel
çalışmalarda kullanılmak üzere Tunçbilek ve Soma bölgelerinde konumlanmış, işletmesi devam
eden dört farklı lavvardan kömür numuneleri temin edilmiştir. Deneysel çalışmalarda kullanılmak
üzere Hacettepe Üniversitesi Maden Mühendisliği Bölümü’nde geliştirilen triboelektrostatik
ayrım düzeneği 35 kV’a kadar statik yük üretebilmektedir. Gerekli statik yükün sürtünme
ile sağlanmasına ilişkin öncül testleri takiben kömür numuneleri ile zenginleştirme işlemleri
gerçekleştirilmiştir. İki ayrı bölgeden temin edilen dört farklı kömür numunesi ile gerçekleştirilen
deneysel çalışmalar sonucunda, triboelektrostatik ayrım ile kömürün yapısına bağlı olarak ince
tane boylarında %50’leri aşan kül uzaklaştırma verimleri elde edilebildiği görülmüştür.
