Mine Scale Constrained Geophysical Inversion; A Case Study at the Darlot-Centenary Gold Mine

Grinding Circuit at Mouteh Gold Mine

This study was conducted in Mouteh grinding circuit. Mouteh gold processing plant is located in Esfahan province,center of Iran, close to Mouteh open pit mine. One of the main problems in this circuit is low efficiency grinding operation. In this study, first grinding circuit and its performance parameters are evaluated. Laboratory and corrected operating Bond work index subsequently were calcu...

Tools to Mine the Gold

Case study of controlled recirculation at a Wyoming trona mine.

Controlled recirculation has been used in the metal/nonmetal mining industry for energy savings when heating and cooling air, in undersea mining and for increasing airflow to mining areas. For safe and effective use of controlled district recirculation, adequate airflow to dilute contaminants must exist prior to implementation, ventilation circuit parameters must be accurately quantified, venti...

Last Words: Amazon Mechanical Turk: Gold Mine or Coal Mine?

Recently heard at a tutorial in our field: “It cost me less than one hundred bucks to annotate this using Amazon Mechanical Turk!” Assertions like this are increasingly common, but we believe they should not be stated so proudly; they ignore the ethical consequences of using MTurk (Amazon Mechanical Turk) as a source of labor. Manually annotating corpora or manually developing any other linguis...
