An Assessment of Existing Production and Revenue Capacities for Artisanal and Small‐Scale Granite Mining in Southwest Nigeria
並列摘要
This study presents an assessment of production capacity of artisanal granite mining in Nigeria. A production rating scale was developed by applying information obtained from site operators of over 5years experience using a prepared questionnaire, and a proposed production equation. Production was categorized into three conditions: ＂fair, ＂poor＂ and ＂worse＂. Production and revenue in tonnes per month were calculated for each site. The obtained result was statistically analyzed to obtain useful values. An analysis of results established that both production and revenue ratings of most sites (56%) are in the poor and worst states. ＂Fair＂ production ranges between 227 and 1500 tonnes per month. This is equivalent to between 408,600 and 2,700,000 naira per month, and substantial. It was concluded that granite ASM has the capacity for employment generation and should be encouraged by Government.
