Bu çalışmada, lateritik nikel cevherlerinin hidrometalurjik işlemlerinde nikel ve kobalt ayırma
ve saflaştırılmasında kullanılan solvent ekstraksiyon (SX) yöntemi için kısa bir değerlendirme
yapılmıştır. Bu çalışma iki bölümden oluşmaktadır. Sülfat liç çözeltilerinden nikel ve kobalt solvent
ekstraksiyonu ilk olarak tanımlanmıştır. Solvent ekstraksiyon tekniğinin bulunduğu lateritik nikel
cevherlerinin işletimi için geliştirilen hidrometalurji tesisler ikinci olarak tartışılmıştır. En önemli
ekstraktantlar ilk bölümde kısaca verilmiştir. Laterit liç çözeltisinde bulunan safsızlıklardan nikel
ve kobalt ayırma ve saflaştırma işlemi ya tekli ekstraktant sistemi olarak adlandırılan direkt solvent
ekstraksiyon (DSX) ya da iki veya daha fazla ekstraktant karışımından oluşan sinerjistik solvent
ekstraksiyon (SSX) yöntemleriyle gerçekleştirilebileceği görülmüştür. Karışık sülfür çökeleği
(MSP) ve karışık hidroksit çökeleği (MHP) işlemlerinden bahsedilmiştir. Bu makale aynı zamanda
her bir ekstraksiyon sisteminin avantaj ve dezavantajlarını ele almaktadır. İlk yatırım maliyeti,
işlem maliyeti ve minerolojik yapının lateritik nikel cevheri için uygun bir hidrometalurjik yöntem
seçimini etkileyebilen en önemli faktörler olduğu görülmüştür.

In this study, a brief overview of the solvent extraction (SX) application for the separation

and purification of nickel and cobalt in hydrometallurgical processing of laterite nickel ores is

presented. This paper consists of two parts: firstly, the SX of nickel and cobalt from sulphate

leach solutions is described; and secondly, the development of hydrometallurgical plants for

the processing of laterite nickel ores that involve solvent extraction technique is discussed. The

most important extractants are shortly given in the first part of the study. It is seen that the

extraction and separation of nickel and cobalt from the impure leach solution of laterite nickel

ores can be performed by either using a single extractant system that is called as a direct solvent

extraction (DSX) or a mixture of two or more extractant which is known as a synergistic solvent

extraction system (SSX). Mixed sulphide precipitation (MSP) and mixed hydroxide precipitation

(MHP) processes are mentioned. This paper is also addressed advantage and disadvantages of

each extraction system. It is shown that capital investment expenditure, operational investment

expenditure and mineralogical content are the most important factors that can affect the selection

of the appropriate hydrometallurgical process for lateritic nickel ore.
