Borates in Metallurgy and Gold Refinement Alloys
Upon cooling, slags from some processes form weak rock-like material that slowly disintegrates, forming dust and mud—which is difficult to deal with. Adding a specialized borate to the molten slag has been shown to prevent these destructive density changes. The slag cools in a stable way, resulting in a slag off-take in the form of fist-sized rocks and minimal dust—and a safer, cleaner
