Development of Geometallurgical Indices for Semi-Autogenous Grinding at Sarcheshmeh Porphyry Copper Mine

Geometallurgy tries to predict the instability the behavior of ores caused by variability in the geological settings, and to optimize the mineral value chain. Understanding the ore variability and subsequently the process response are considered to be the most important functions of an accurate geometallurgical study. In this paper, the geometallurgical index is presented as a new tool to...

Gold recovery by KC from grinding circuit of Bergama CIP plant

Numerous research studies have been done to improve the gold recovery methods and to fi nd alternative processing techniques in the last decade. The main goal in this search has become to design an effi cient plant employing environmentally acceptable processes today. For this purpose, the application of environmentally friendly, no chemical included techniques like centrifugal gravity separato...

Hearing protection device usage at a South African gold mine.

BACKGROUND Occupational noise-induced hearing loss (NIHL) occurs in many industries despite interventions such as hearing conservation programmes. AIMS To determine the actual and reported use of hearing protection devices (HPDs) in noise-exposed gold mine workers and their reported knowledge, attitudes and practices relating to NIHL and HPDs. METHODS A cross-sectional descriptive study was...

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...

Facilitate of Gold Extracting From Mouteh Refractory Gold Ore Using Indigenouse Bacteria

The term biomining have been coined to refer to the use of microorganisms in mining processes as in the biooxidation of refractory gold minerals. The biooxidation of refractory gold ores presents similar characteristics when compared with roasting and pressure oxidation. Almost without exception, microbial extraction procedures are more environmentally friendly. The isolated bacteria in this st...
