uses of zinc. sterling hill was a zinc mine, and the last operating underground mine in the state of new jersey. It closed in 1986 after more than 138 years of almost continuous production, during which it yielded more than million tons of zinc ore. the ore was fabulously rich, averaging more than 20% zinc, and occurred in thick seams that were worked to a depth of 2,550 ft below the

zinc is brittle, but it becomes malleable at 100 zinc, a blue-gray, metallic element, is a moderately good conductor of electricity. the most common alloy is brass, which is a mixture of zinc and copper. relation to mining. zinc is recovered from a number of different zinc minerals. the most significant of these is sphalerite.
there are four main mining methods: underground, open surface placer, and in-situ mining. underground mines are more expensive and are often used to reach deeper deposits. surface mines are typically used for more shallow and less valuable deposits. placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments.
