Rambler Metals & Mining (RMM) currently operates the Ming Mine and ore processing plant on the Baie**Verte Peninsula of Newfoundland and Labrador. The Ming Mine produces both copper and gold. The**objective of this proposed study is to gain information through geometallurgical analysis of current process**stream materials, via advanced and innovative instrumental Mineral Liberation Analysis (MLA). The findings**will then inform changes to processing to increase gold recovery in a cost-effective manner.**Mineral Liberation Analysis (MLA) is based on high resolution Scanning Electron Microscopy (SEM). Our**planned approach will include improved integration of efficient automated MLA mapping, using an SEM**equipped with a Field Emission Gun (FEG) electron beam source that provides superior spatial resolution for**this application, with follow-up Backscattered Electron Imaging - Energy Dispersive X-Ray Spectroscopy**(SEM-BSE-EDX) analysis to characterize individual gold-bearing mineral grains.

Rambler Metals & Mining (RMM) 目前在纽芬兰和拉布拉多省 Baie**Verte 半岛经营 Ming 矿和矿石加工厂。明矿同时生产铜和金。这项拟议研究的**目标是通过先进和创新的仪器矿物解放分析 (MLA) 对当前工艺**流材料进行地质冶金分析来获取信息。然后，研究结果**将为加工过程的改变提供信息，以经济高效的方式提高黄金回收率。**矿物解放分析 (MLA) 基于高分辨率扫描电子显微镜 (SEM)。我们**计划的方法将包括改进高效自动化 MLA 映射的集成，使用配备场发射枪 (FEG) 电子束源的 SEM**，为**此应用提供卓越的空间分辨率，并进行后续的背散射电子成像- 能量色散 X 射线光谱**(SEM-BSE-EDX) 分析，用于表征单个含金矿物颗粒。
