Cobalt and nickel are found together in nature in a large number of deposits. Mining of these metals, together with others technologically associated with electronic advances, is being reactivated to guarantee growing supplies; especially for the fields of batteries, energy accumulation and the decrease in the volume of these essential components for our mobiles, computers, hybrid and electric vehicles. These extraction processes have to evolve from optimised technologies to deal with deposits with a lower metal content. Cobalt and nickel are two elements that are well positioned in new technologies, especially those with an energy link.

Processing of PGM involves comminution, flotation, smelting, converting, base metals refinery and precious metals refinery. Due to increasing chrome content in the feed and the challenges associated with operating high chrome feed, alternative routes to smelting of PGM are being investigated. Some hydrometallurgical routes have been proposed. However, none of the reported potential routes have yet been commercialised. PGMs together with gold and silver are classified as noble or precious metals because of their high corrosion and oxidation resistance [ 1 , 2 , 3 ].


The smelting of laterite ores to produce ferronickel is based on two principles. The first principle is that nickel and iron oxides are easily reduced to metallic nickel.

Kell hydrometallurgical process for extraction of platinum group metals and base metals from flotation concentrates. Liddell I ; M. Adams II. The Kell Process has been developed for the extraction of platinum group metals PGMs and base metals from sulphide flotation concentrates.

The Recovery of Nickel from its Ores

It focuses on present day processes and future developments rather than historical processes. They all are, for example, important catalysts — with platinum group metals being especially important for reducing car and truck emissions. Stainless steels and CoNiFe airplane engine super alloys are examples of practical usage.

И в следующее мгновение не осталось ничего, кроме черной бездны. ГЛАВА 102 Стратмор спустился на нижний этаж ТРАНСТЕКСТА и ступил с лесов в дюймовый слой воды на полу. Гигантский компьютер содрогался мелкой дрожью, из густого клубящегося тумана падали капли воды. Сигналы тревоги гремели подобно грому. Коммандер посмотрел на вышедший из строя главный генератор, на котором лежал Фил Чатрукьян. Его обгоревшие останки все еще виднелись на ребрах охлаждения.

Но Стратмор понимал, что Хейл не станет долго держать язык за зубами. И все же… секрет Цифровой крепости будет служить Хейлу единственной гарантией, и он, быть может, будет вести себя благоразумно. Как бы там ни было, Стратмор знал, что Хейла можно будет всегда ликвидировать в случае необходимости. - Решайтесь, приятель! - с издевкой в голосе сказал Хейл.  - Мы уходим или нет? - Его руки клещами сжимали горло Сьюзан.
