WebFeb 16, 2024 · Smelting: Then, copper concentrates are mixed with silica (sand) and limestone and heated in a furnace to form two naturally-separating layers. One layer is a waste containing iron and silica compounds and is discarded as slag slag Byproduct left after a desired metal is thermally separated from its raw ore. .
WebHow effing cool is that?! This information can be useful for making bronze (copper/tin/lead) or for smelting other metals into ingots for preservation. Anyway, thanks for the instructable, theres a good chance Ill make one myself someday. The idea about making an induction furnace, or possibly a stick welder from the transformer is a good one too. WebThe primary purpose of matte smelting is to melt and recombine the charge into a homogeneous matte of metallic copper, nickel, cobalt, and iron sulfides and to give an iron and silicon oxide slag. It is done in many types of furnace on both roasted or unroasted sulfide feed material. The reverberatory furnace is essentially a rectangular refractory …
