Nonmetallic Minerals Process Method Some non metallic minerals that actually are sources of metals are included because of the important application of flotation as a means of freeing them from associated minerals that are of no value so that the resulting concentrate may However some slags may contain remnant minerals that can be a potential source of metal release to the environment Acid rock drainage from waste rock Although the character of waste rock varies with the type of ore many waste rocks contain sulfide minerals associated with metals such as lead zinc copper silver or cadmium
