Colouring of dolomite, quartzite and dolerite mine dump rocks
Abstract
For environmental and aesthetic purposes it has
become essential that mine dump rocks either blend into the
environment or be used in the production of other products.
Lately, there has been a constant need to produce more durable
road and construction material and to develop an alternative for
granite countertops and flooring. For the visibility of road surface
material and the aesthetic aspect of countertops, the colouring of
mine dump rocks was considered. A cost effective and
environmentally friendly process was suggested to colour mine
dump rocks. In this study different colouring agents for three mine
dumping rocks, dolomite, quartzite and dolerite, were
investigated. The aim was to create lasting colours that have a high
wear resistance to weather conditions. Coloured dolomite can be
used as road and construction material, coloured quartzite as
countertops while coloured dolerite can serve as a replacement for
road surfaces
