    Nickel ore might be abundant these days, but that wasn’t the case in the past and, like most things, this excess will be over in a near future. According to a British Geological Survey, referred by the site Metal Miner, 73 percent of the continental world nickel resources are lateritic. Still, the current dominant extraction process, called High Pressure Acid Leach (HPAL), is technologically
