Traditional forms of mining can be unsafe for workers. Fires and collapses can be deadly, and the health effects of mining can be devastating. Others, however, object to mining in general. Because coal and oil release carbon dioxide when used as fuel, some argue that mining exacerbates global warming. Others object to mining for the rare …

Consider this: if you are mining a laterite nickel ore grading 1%, and you want to make 60,000 tonnes a year of nickel, you need to mine at least six million tonnes of material. With HPAL, you have to place all of that mined material into an autoclave (think of a submarine-sized pressure vessel), adding heat, adding sulphuric acid, and ...
