Roadmap for the Management of Mineral Gangue - Pyrite and the Environmental Cost Impact

Abstract

Green and smart mining in today’s industry has become one of objectives target to be fulfilled by the mining operator, it respectively in looking into current and future challenges of climate changes along the strategy implementation of decarbonization and energy conservation. The orebody containing negative characteristic of geochemical lead into the needs of effort to handle them in later stage of mining process. It’s created an extra cost due to the needs to perform activities meeting standard compliance and or paying the consequences following fail in fulfil the contractual obligations. Composition of metal concentrate containing un-expected residual mineral or gangue could create an extra effort for the facility of metal refinery or smelter for handle it. Especially at containing gangues who can negatively impacted and suffering the environmental. The better understanding of value impact since this presenting of negative chemical ores can further provide a sufficient program and preparation of resources upfront for risk mitigation. On the other side of risk positive, there is benefit generated by use this pyrite on another application. It then calls for a need of resources to handling and converting them to become valuable product for selling. Planning for resource allocation under the establish program to better of managing the risk and lead into success of organization to execute the target. It therefore there are two essential things shall organization be considered in address this, they are: establish roadmap or program for properly managing the pyrites and make the determination at the needs of resources to be allocated into each activity under it’s setup roadmap. This written paragraph aiming exercise the key criteria in establishing the roadmap of handling pyrites by firstly understand the cost consequences into the living environmental at the do-nothing action. The determination of roadmap itself is achieved by conducting the risk assessment to early engineering design process activities and the effectiveness of exist control with residual risk to be continue review and monitor under the setup of roadmap program.
