All of the slag produced hopefully ends up in the form of a drippy block in the pit. This type of smelting is typical of early time periods (Iron Age) and usually involves quite large furnaces. It generally begins to be replaced by (often smaller) slag-tapping furnaces during the course of the 1st millennium AD.

At this level of reduction, 91% of the iron was retained in the slag phase, while only 50% of the cobalt, 63% of the copper, and 83% of the nickel were recovered to the alloy. It was found that injection of pulverized coal greatly improved the reduction, and hence the recovery, of nickel and cobalt oxides from the slag.

Slag Wikipedia

The smelting of copper, lead and bauxite in non-ferrous smelting, for instance, is designed to remove the iron and silica that often occurs with those ores, and separates them as iron-silicate-based slags. Slag from steel mills in ferrous smelting, on the other hand, is designed to minimize iron loss and so mainly contains oxides of calcium, silicon, magnesium, and aluminium.
