open cast mining of nickel ore
....Compared to many open pit operations, Hanna Nickel used small shovels and trucks. I believe these we 75 ton trucks and the shovels were not very large compared to the iron ore oerations and coal operatons I had the prvilage to be associated with. The ore content was about 1% nickel and there were truck mounted analysis labs that tested the ore content of what was being mined. If "higher" grade ore was found in a pocket it was mixed with lower grade ore to allow a consistant product to be sent to the smelting operation at the bottom of the hill. ... source

nickel applications
...Nickel is primarily sold for first use as refined metal (cathode, powder, briquet, etc.) or ferronickel. About 65% of the nickel consumed in the Western World is used to make austenitic stainless steel. Another 12% goes into superalloys (e.g., Inconel 600) or nonferrous alloys (e.g., cupronickel). Both families of alloys are widely used because of their corrosion resistance. The aerospace industry is a leading consumer of nickel-base superalloys. Turbine blades, discs and other critical parts of jet engines are fabricated from superalloys. Nickel-base superalloys are also used in land-based combustion turbines, such those found at electric power generation stations. The remaining 23% of consumption is divided between alloy steels,
environmental problems on the philipines
...Location: Manicani Island, Guiuan, Eastern Samar, Philippines Manicani is a small island in the beautiful Municipality of Guiuan, Eastern Samar. Guiuan is a 3hr ride by land from the region's capital (Tacloban City), and approximately 30min ride by a bangka from Guiuan proper. The island is inhabited by more or less 100 families that primarily depends their livelihood on fishing and farming. The island is rich in its marine wealth with its prestine crystal clear waters, diverse species of sea grasses, corals, mangroves, and fishes. Now, this small island (approximately 12km in circumference) has been greatly abused because of its rich mineral deposit of nickel ore. The saga of mining in Manicani Island has caused much chaos to the inhabitants; in fact, two lives have been lost already, one was a child and the other an engineer....
