The two of the best known processes are smelting and roasting. The two are actually different methods but both involve heating the ore to high temperatures. Technically any methods which consist of processing ore by heating it are called “pyrometallurgy”.
Mining processes require steady and reliable delivery of fresh and reclaimed water for processing heating cooling and more. Flowserve gives users the most flexibility in pump type and size selection ensuring optimum operating efficiencies. Slurry Pipelines
