1. Introduction. Nickel and cobalt are essential strategic metals that are widely employed in alloy materials, battery materials, and other industries because of their beneficial properties [1], [2].Nickel resources are broadly classified as nickel sulfide ore and laterite ore, with nickel sulfide ore accounting for only about 30% of total nickel resources.
Primary nickel is produced from both lateritic and sulfidic ores. Lateritic ores are formed by prolonged weathering of ultramafic rocks. The laterite deposits exhibit graded layers of ore, with high iron, low nickel ore on top and low iron, high nickel ore below. The...
Nickel (Ni) is a transition element that exhibits a mixture of ferrous and nonferrous metal properties. It is both siderophile (i.e., associates with iron) and chalcophile (i.e., associates with sulfur). The bulk of the nickel mined comes from two types of ore deposits: magmatic sulfide deposits where the principal ore mineral is pentlandite ...

Furthermore, various copper and nickel ores are processed by two main methods – hydro-metallurgical and pyrometallurgical.
A number of new hydrometallurgical processes are being developed for the extraction of nickel and cobalt from nickeliferous laterite ores. Many of these processes require the dissolution of the metal values with sulfuric acid at high temperature (245°-270° C.) and pressure (525-785 psig), followed by solid-liquid separation and neutralization of residual …

1. Introduction. Cobalt is a valuable metal found in the earth's crust which is extensively used in a wide range of industrial and military applications (Tkaczyk, Bartl, Amato, Lapkovskis, & Petranikova, 2018).In recent years, due to the diverse range of its industrial application, the demand for cobalt has increased significantly and, as a result, …
Laterite ores contain several kinds of metal elements including nickel, cobalt, iron, silicon, aluminium and chromium. 40% of world's annual nickel production is from low-grade laterite ores [1, 2]. Sulphides are the high-grade nickel ores and typically range from 1 to 4%.

Introduction For many years, the nickel and cobalt were dominantly produced pyrometallurgically from the sulfide ores. The nickel sulfide ores account for approximately 30 % of the global nickel deposits, the rest of the nickel in Earth's crust is contained in laterites – an oxide ores. Nickel production from sulfide ores is reaching a ...
Cobalt is almost always a by- or co-product of mining for other metals, chiefly nickel and copper or it can be found in cobalt deposits on the sea floor.
Nickel is associated with cobalt in laterite oxide ores, and all the other Ni-based byproducts derive from Mg content. The extraction efficiency of nickel depends on selecting a suitable processing route and the ore mineralogy along with …
The extent of substitution has a significant impact on the dissolution behavior of laterite minerals. In laterite nickel ores where nickel and cobalt are disseminated in different associated/interlocked minerals, the ore mineralogy type can dramatically impact H 2 SO 4 leachability and consumption rate (Luo et al., 2015). Until recently, Sc, a ...
2.2.6 Cobalt from Central African Copper–Cobalt Ores. While most cobalt (~ 50%) is produced as a coproduct from the processing of nickel/cobalt ores, a significant amount of cobalt (~ 35%) is produced from Central African copper–cobalt ores. The remaining ~ 15% is produced from other primary sources, such as Moroccan cobalt–arsenic ores.
The name cobalt is derived from "kobald," a German goblin. The term was first applied in the 1500s by miners who, when attempting to smelt ores for copper or nickel, also ended up with a cobalt oxide compound that often volatilized arsenic oxide, thereby adding to the infamy of the ore.
Cobalt is a strategic and critical mineral whose demand is expected to grow rapidly. This study aims to provide a comprehensive summary of cobalt extraction and recovery research from 2012 to 2021 in the form of bibliometric analysis.
