Grafit, çeşitli fiziksel ve kimyasal özelliklerinden dolayı birçok farklı endüstride kullanılmaktadır. Doğal grafit, farklı fiziksel özelliklere, görünüme ve kimyasal bileşime sahip olan amorf grafit, pulsu grafit ve kristal damar grafit olmak üzere üç ana tipte sınıflandırılır. Uygulama çeşitliliğine göre grafit talebi son yıllarda önemli ölçüde artmıştır. İyi kalitede grafit konsantresi elde etmek için zenginleştirme yöntemleri yaygın olarak uygulanmaktadır. Grafitin zenginleştirme yöntemini belirleyen başlıca parametreler cevherin iri veya ince kristalli oluşu, karbon içeriği, cevherdeki gang minerallerinin türü ve serbestleşme tane iriliğidir. Doğal hidrofob olması nedeniyle flotasyon, grafit cevherleri için başlıca zenginleştirme yöntemidir. Bununla birlikte gravite ile zenginleştirme, manyetik ayırma, elektrostatik ayırma metotları ve liç yöntemleri de uygulanmaktadır.
