cobalt–nickel mines, and 5–10% comes from cobalt-copper-nickel mines (Tisserant and Pauliuk 2016). Because of the complex mineral state of the cobalt-bearing ore and the large dierence in selectivity, obtaining cobalt products directly by otation is dicult.

As a result cobalt-containing ores are not mined primarily for their cobalt content, but rather cobalt is produced as a by-product, particularly from the production of copper, …
Cobalt present in the ferronickel is not of any economic value in this form. In 2005, 30% of the world's nickel production was contained in ferronickel produced from laterite ores [6]. Ferronickel production begins with moist garnierite concentrate. Garnierite concentrates usually have nickel grades of 1.5–3% Ni.

Unlike other metals, cobalt is rarely found in its pure form. A small quantity is produced specifically from one of a number of metallic-lustered ores, such as cobaltite (CoAsS). However, the vast majority comes from ore usually produced as a by-product of copper and nickel mining. An increasing percentage also comes from recycling products ...
