Nickel. Nickel is silverywhite. hard, malleable, and ductile metal. It is of the iron group and it takes on a high polish. It is a fairly good conductor of heat and electricity. In its familiar compounds nickel is bivalent, although it assumes other valences.
The Philippines, which has 29 nickel mines and two nickel processing plants, usually ends its mining season in October, when heavy rains and strong winds hamper mining and shipping operations. Production resumes in March or April of the following year. Indonesian ore was generally of a higher grade than ore from the Philippines, he noted.
There are many different ways to procure copper from buried ore. The mining process begins with extraction of the ore from the ground. The ore then goes through smeltering and converting and the process ends with the refined ore being made into copper plates ready for sale to the world market (Figure 1) (2,3,4).
Nickel occurs in ore bodies, and breaking down these ore bodies to extract nickel expends energy. Producing nickel requires ample supplies of coal, electricity and crude oil. Mines and blast furnaces utilize energy to extract nickel ores from the ground and process it into nickel. These costs can have a big effect on primary production.

In a nutshell, the Indonesian government instituted a ban on nickel ore exports in an effort to encourage investment in downstream nickel ore smelting operations. Prior to 2014, China, the largest importer of Indonesian nickel ore, would ship the raw nickel ore back to its smelters, where it would be processed into nickel pig iron (NPI).

Health effects. Note: The health effects are highly dependent on the manner and degree of exposure and on the exact chemical ''species'' in which the nickel atoms are allergic effects tend to arise from the Nickel cation Ni ++, but it is not entirely clear which chemical species is reponsible for the carcinogenic effects noted much more commonly in the past.

Nickel is commonly present in two principal ore types—sulfide or laterite. Sulfide ores are typically derived from volcanic or hydrothermal processes and usually include copper (Cu) and/or cobalt (Co), and often precious metals such as gold (Au) or platinum (Pt), palladium (Pd) and rhodium (Rh) (the platinum group metals or PGMs) (Naldrett, 2002, Hoatson et al., 2006).
