Iron oxides can be applied as adsorbents to remove harmful substances from the water used
in the textile process. If these oxides can be synthetized through acid digestion of ferrous …

The growing demand for nickel and cobalt increases the interest in extracting metals from
secondary sources, such as flotation tailings. A preferential strategy for the processing of the …

Rare earth elements (REEs)-based (NdFeB) magnets and lithium− ion batteries (LIBs) are
critical for a low− carbon economy. Their production depends on critical elements like REEs …

Nickel is a strategic resource in social life and defense technology, playing an essential role
in many fields such as alloys and batteries. With the decrease in nickel sulfide, it is of great …

The aim of this study was to precipitate goethite from high-iron (II)-bearing atmospheric and
heap leach solutions of lateritic nickel ore generated either by reductive leaching of the ore …

ABSTRACT A two-step closed circuit, operated at 90–95ºC, was found suitable for practical
iron removal from real sulfuric acid leach liquors, resulting in low losses of nickel and cobalt …

A calcified roasting− acid leaching process was developed as a highly effective method for
the extraction of valuable metals from low nickel matte in the presence of CaO additive. The …

The abiotic mineralization of ferrous ions for ZnSO 4-FeSO 4 solution at temperatures of
368.15–423.15 K was investigated. The effect of kinetic factors including oxygen partial …

The separation of Cr (III) from the polymetallic leaching solution is a typical problem
encountered during the recycling of electroplating sludge. In this paper, a novel method was …

Basalt-hosted monocentric agates from Bou Hamza (Morocco) were examined to unravel a
discrete relationship between moganite content, water content, and the abundance of …
