Smelting of roasted (calcine feed) or unroasted (green feed) ore concentrate produces matte, a molten mixture of copper sulfide (Cu2S), iron sulfide (FeS), and some heavy metals. Converting the matte yields a high-grade "blister" copper, with 98.5 to 99.5 percent copper.

For ore, the ideal size ranges between ‘pea to rice’ size - 5 to 2 mm, but retaining the 'dust'. Ore too fine may simply blow back out of the furnace, and tends to absorb excess carbon. Too large and the particles will not completely reduce to metallic iron. Some ore types should be roasted before breaking and adding to the furnace.
