4.3.1: Surface Mining Methods. Surface mining methods are traditionally divided into two classes: mechanical and aqueous.Mechanical methods rely on breaking the ore by mechanical means, and aqueous methods rely on the use of water or another solvent, e.g. an acid, to break down the ore and facilitate its removal.
