ABSTRACT:
Authentically, this case study shows that,
proactive approach to resolve reagent input supply problems at the Process
Plant of Goldfields Ghana Limited-Tarkwa Mine is the key to ensuring higher
productive and competitive advantage in today’s business environment.
Pragmatically, the cases studied revealed the existent to which reagent control
models used at Goldfields Ghana Limited-Tarkwa Mine and pointed out the lack of
advance warnings with regard to reagent inventory control chart, quality
control model and lime consumption control method. Additionally, the minimum
and maximum model application has limited control over inventory to meet abrupt
changes in rate of usage. Clearly, the paper identifies lack of proactive
measures in the area of limits set for taking corrective actions of the various
models. Notably, the future warning signal of slope analysis depends on the
focus of the given reference variables. Consequently, convergence of opposing
focus variables depicts a deteriorating future while’s divergence point to a
better future. Conversely, convergence of similar focus variables point to
better future while as divergence indicates deteriorating future. The paper
recommended applicable slope analysis approach as complementary methods to
enhance proactive assessment of all the reagent control models to ensure the
achievement of competitive advantage in the company’s endeavour. Cost and
consumption variances analysis model was the further research work recommended
by this paper as another method that will go a long way to enhance proactive
reagent control at the Goldfields Ghana Limited-Tarkwa Mine Mineral Processing
Plant operations.
