Abstract
The mining sector is one of the key economic drivers in Southern Africa. However, due to
mining and minerals processing activities, huge amounts of waste are generated that have
potential negative impacts to the environment. Various wastes such as wastewater, particulate
gases, overburden, waste rocks, tailings and slag are generated during the value addition of
the ores. Although there is potential for metal recovery and wastewater re-use from this waste
generated it is critical that before a mining activity is done, an environmental impact
assessment be done for sustainable mining activities.
Keywords: Environment, mining, waste management, value addition
1. Introduction
The mining industry is one of the industries that contributes significantly to the gross domestic product (GDP)
capita of all mining countries, in Zimbabwe alone, the mining sector contributes at least 8% towards the GDP
(Adler and Rascher, 2007; Hawkins 2009; Malinga, 2018). Table 1 gives a summary of the GDP growth in the
mining sector.
