This document discusses recycling and environmental protection. It summarizes the use of various waste materials like marble, granite, metal slag, and black sand waste. It then provides details on basalt, describing it as a hard, black volcanic rock composed of minerals like olivine and pyroxene. New paints have been developed using natural and melted basalt as pigments by incorporating their micro and nano-particles. The chemical compositions of natural and melted basalt are also examined. Finally, it briefly mentions mining waste and thermoplastic recycling.

16. Natural & Melted Basalt

17. Basalt is not a mineral, because is can not be expressed in a definite
chemical equation, nor does it have a definite crystal structure. Basalt is
a hard, black volcanic rock with less than about 52 weight percent silica
(SiO2). Common minerals in basalt include olivine, pyroxene, and
plagioclase. Basalt is erupted at temperatures between 1100 to 1250° C.
When basalt is beneath the surface it is called lava, when it is outside
the earth's crust, it is basalt.

18. New Paints from basalt
New painting was developed from natural
basalt and from melted basalt which is by
product in rock wall industries. In new
paints, natural basalt and melted basalt
were employed as the pigment, the
m i c r o a n d n an o - p ar t i c l es w er e
incorporated in paint formulations in
different concentrations for comparison.
