This case study authentically demonstrates that a proactive approach to resolving reagent input supply problems at the Process Plant of Ghanaian Mine, Tarkwa is the key to ensuring higher productivity and competitive advantage in today's business environment. Practically, the cases investigated revealed the existence of reagent control models used at the Ghanaian Mine, Tarkwa, as well as the lack of advance alerts about reagent inventory control charts, quality control models, and lime consumption control methods. Furthermore, the minimum and maximum model applications have restricted inventory control to accommodate rapid shifts in consumption rates. Clearly, the paper identifies lack of proactive measures in the area of limits set for taking corrective actions of the various models. Notably, the focus of the given reference variables determines the future warning signal of slope analysis. As a result, convergence of opposing target variables indicates a worsening future, while divergence indicates a brighter future.Convergence of identical focus variables, on the other hand, suggests a better future, while divergence indicates a worsening future. The paper suggested using a slope analysis methodology as one of many complementary approaches for improving constructive evaluation of all reagent control models and ensuring a competitive edge in the company's endeavour. This paper recommends more research into the cost and usage variances analysis model as another tool for improving proactive reagent control at the Ghanaian Mine, Tarkwa, Mineral Processing Plant operations.
