Grafit: Bir Genel Değerlendirme

Öz

Özet: Özellikleri nedeni ile stratejik hammaddeler arasında yer alan grafitin kullanım alanları çok geniştir. Mükemmel ısı ve elektrik iletkenliği ve ısıya dayanıklılık gibi çok önemli özellikleri nedenleriyle günümüz teknolojisinin vazgeçilemeyen endüstriyel hammaddesi olan grafit; ateşe ve asitlere karşı dayanıklığı nedeniyle döküm ve refrakter sanayiinde, pota ve laboratuvar malzemeleri yapımında, yüksek elektrik iletkenliği ile elektrod, motor fırçaları, pil çubukları ve elektronik aletlerin imalinde, yumuşaklığı nedeniyle, kurşun kalem yapımı ve hareketli metal aksamlarının yağlanmasında, bunlara ilaveten siyah renkli ateşe dayanıklı boyalarda, motor yağlarında katkı malzemesi olarak, lastik, araba balataları imalinde kullanılmaktadır.   Bu teknik araştırmada bir karbon minerali olan grafitin özellikleri-sınıflandırılması, üretimi-tüketimi, kullanım alanları, ve zenginleştirme teknolojileri ile ilgili bilgiler verilmiş, Dünya’da ve Ülkemizde yapılan zenginleştirme çalışmalardan elde edilen sonuçlar özetlenmiştir. Abstract: Regarding its properties graphite which is a strategic raw material has wide range of usege areas.  Graphite has excellent heat and electical conductivity and it is also resistant to heat. Due to abovementioned reasons, graphite is irreplaceable material for industy. In order to give examples, casting and refractory industry utilize graphite due to its resistant to heat and acids, it is also used in laboratory materials and crucible production, due to its high electric conductivity electrode, battery bars, engine brushes and electronical devices production. And due to its softness pencil production and oiling of moving metalic parts, and also black colored durable to high heat dye production, engine oil production, tyre and balata production graphite is used as additive material.   In this techical research, properties, classification, production and comsumption, usage areas and beneficiation processes of graphite which is actually carbon mineral is explained. Beneficiation studies in our country and in the World and results of these studies were summarized in this study.
