* Indonesian government temporarily revoked nickel ore and bauxite export permits of four companies citing zero progress in smelter development, energy ministry data showed on Thursday. * Export permits for a combined 4,222,119 tonnes of nickel ore were revoked from PT Surya Saga Utama, PT Modern Cahaya Makmur and PT Integra Mining Nusantara, the data showed.
Nickel (Ni) is a transition element that exhibits a mixture of ferrous and nonferrous metal properties. It is both siderophile (, associates with iron) and chalcophile (, associates with sulfur). The bulk of the nickel mined comes from two types of ore deposits:

The London Metal Exchange has received an application to list gradeI cobalt cut cathodes produced by Norilsk, it specified in a note to members on Friday April 5. The application marks the first time a new brand has been listed since the LME opted to suspend brand listing fees .
Production. Impurities (iron, nickel, copper, zinc) are removed and cobalt is precipitated in its hydroxide form using lime. Cobalt metal can then be refined from this using electrolysis, before being crushed and degassed to produce a pure, commercial grade metal.
The results showed that there is no benefit gained in the leaching of nickel by grinding finer than mm. Cobalt extraction increased with decreasing size fractions because of coarse and compact manganese oxides particles that associate with cobalt in the laterite ore ( Kursunoglu and Kaya, 2016 ).

A number of recent bulk carrier losses have been attributed to the liquefaction of different ore cargoes, especially nickel ore. The mandatory application of the International Maritime Solid Bulk Cargoes (IMSBC) Code enhances the safety of bulk carriers through the setting of .
For a long time nickel was not recognised as a metal in its own right, but was instead regarded as a nonmeltable component of copper ore. This view was not refuted until the 18th century.
Most nickel ores have several recoverable metals in them and the process if commonly a multiple stream of metals recovered. The copper concentrate is sent to the copper smelter and % copper cathode is produced in electrowinning cells. The nickel ore is sent to the nickel refinery, where a complex set of reactions is carried out.
Resource distribution. World Resources: Identified landbased resources averaging 1% nickel or greater contain at least 130 million tons of nickel. About 60% is in laterites and 40% is in sulfide deposits. Extensive resources of nickel are also found in manganese crusts and .
