Aluminum Slag: Problems and Solutions - Aluminium Guide

Slag is formed on the surface of melts as a result of interaction with air gases, primarily, with oxygen. Slag is a physical mixture of oxides and other solid compounds, as well as molten metal, which is inside them. Dross, which forms on the surface of the aluminum melt, is an inevitable by-product. Slag is "foam on molten metal" [1].
