pit gold mining project named "Coriorcco Gold", including a project description, an explanation of the main operational parameters, and an economic evaluation of the project. In the economic evaluation, variables as the breakeven cutoff grade (BCOG), stripping ratio
Five primary evaluation criteria were identified and CPFNs were introduced for DMs to adequately describe their opinions under these criteria. Then, the traditional previously fuzzy approaches were integrated to select the optimal mine among three gold mines in the terms of cleaner production.

The risk of arsenic (As) contamination from gold mining is a long-term environmental concern for mines worldwide. Researchers have mainly focused on As contamination induced by tailings, however, less attention has been paid mineralogically to differentiate the fate of As among different As-bearing matrices.
companies in the mining sector. The debate about specific guidance for exploration, evaluation, development and production of mineral resources continues. This publication does not describe all IFRSs applicable to mining entities but focuses on those areas that are of most interest to companies in the sector. The ever-changing
gold within the study is usually coarse in nature with majority of the coarse gold occurring at the upstream of the drainages in the area. Clayey materials also represent large portion of the gold bearing gravels in almost all the sampled areas. Keywords: Placer deposit, Resource Evaluation, Kwabeng, Atewa Range. 1.0 INTRODUCTION . Background
Gold mining uses chemicals that are discharged into rivers without any control when there are no good mining practices, generating environmental and public health problems, especially for downstream inhabitants who use the water for consumption, as is the case in Monterrey township, where the Boque River water is consumed. In this study, we evaluate …

Mines and gold mining operations have become increasingly geographically diverse, far removed from the concentrated supply of four decades or so ago when the vast majority of the world's gold came from South Africa. China was the largest gold producer in the world in 2016, accounting for around 14% of total annual production.
The Wilcox mine workings followed a number of high grade gold veins, primarily on the Wilcox claim, a Crown Granted claim that is currently owned privately by an Oregon resident. Some time around 1900, a small stamp mill was constructed to process ore from the mine at a rate of 10-30 tons per day.

Mining and the related industries play an important role in the Korean economy. The Korean mining industry is relatively small. There are several mines in Korea but they are very small, and production is low in comparison with other countries' mines. Thus Korea must take part in mineral projec ts all over the world to secure essential
