Waste management decisions are a fundamental aspect of strategic mine planning; however, they are frequently simplified when optimising the long-term production schedule and are managed subsequently. In this work, a simultaneous stochastic optimisation approach is applied to a gold. CONTACT Zachary Levinson

The reasons for this are most likely due to the perceived relatively benign nature of mine wastes, remoteness from populations, apparent success in mine waste management, or other factors. Waste rock is generally the only waste type which could pose a significant long term environmental threat, as it could contain significant sulfide mineralization.

· Mining produces a lot of waste which should be disposed of properly. Improper waste disposal leads to soil, water and air pollution. There are various types of mining. They include coal mining, metal, landfill mining, oil and gas extraction and non-metal ore mining. This means there are also different types of mining waste. These

Gold mining is one of the most destructive industries in the world. It can displace communities, contaminate drinking water, hurt workers, and destroy pristine environments. It pollutes water and land with mercury and cyanide, endangering the health of people and ecosystems. Producing gold for one wedding ring alone generates 20 tons of waste.
