Abstract

Mikro analitik teknikler, cevher karakterizasyon calismalarinda yaygin bir sekilde kullanilmaktadir. Altin cevherlerinin, ozellikle refrakter altin cevherlerinin karakterizasyonunda da etkin bir sekilde kullanilan bu teknikler, dogruluk ve hassasiyeti yuksek oldukca faydali bilgiler sunmaktadir. Cevher hakkindaki bu bilgiler dogru proses seciminin yapilmasina ya da mevcut prosesin etkin bir sekilde kontrol edilmesine olanak saglamaktadir. Bu calismada, altin cevherlerinin karakterizasyonunda, mikroskobik (visible) altinin belirlenmesinde kullanilan (QEMSCAN) (Quantitative Evaluation of Mineralogy by Scanning Electron Microscope), MLA (Mineral Liberation Analyzer) gibi SEM (Scanning Electron Microscopy) temelli gelistirilmis modern otomatik analiz yontemlerinin yani sira refrakter altin cevherlerinde mikroskop altinda kolayca gorulemeyen, cok ince ‘invisible’ altinin belirlenmesinde kullanilan EPMA (Electron-Probe Micro-Analysis), μ-PIXE (Microparticle- induced X-ray emission) ve SIMS (Secondary-Ion Mass Spectrometry) gibi yaygin olarak kullanilan mikro analitik yontemler tanitilmakta ve yapilan guncel calismalardan ornekler sunulmaktadir.

阿尔廷政府特征化中使用的微观分析说明

微观分析技术被用于传播珠宝的魅力。这些技术，准确度和灵敏度的黄金首饰，有效地利用了黄金首饰的特点，也是有用的折射器。这些关于珠宝的信息是为了确保执行正确的流程顺序，或者确保在有效的时间控制当前流程。在这篇论文中，将扫描电子显微镜定量评价矿物学用于黄金首饰的特征，用于微观黄金的定义（QEMSCAN）（扫描电子显微镜矿物学定量评价），基于SEM（扫描电子显微镜）的EPMA（电子探针微观分析）作为基于先进现代自动分析组件（如黄金首饰中的警报器折射器）的MLA（矿物解放分析仪），在微观银下不容易保证，但也用于“不可见”金的定义，微粒诱导的X射线发射和SIMS（二次离子质谱法）是用于展开和展开现代calims装饰物（如微粒）的微量分析化合物的展开。

期刊介绍： Scientific Mining Journal, which is published i n open access electronic environment and i n printed, is a periodical scientific journal of Union of Chambers of Turkish Engineers and Architects Chamber of Mining Engineers. The name of the journal was "Mining" until June 2016 and it has been changed to "Scientific Mining Journal" since September 2016 because it can be confused with popular journals with similar names and the ISSN number has been updated from 0024-9416 to 2564-7024. Scientific Mining Journal, published four times a year (March-June-September-December), aims to disseminate original scientific studies which are conducted according to the scientific norms and publication ethics at national and international scale, to scientists, mining engineers, the public; and thus to share scientific knowledge with society. The journal is in both Turkish and English. The journal covers theoretical, experimental, and applied research articles, which reflects the findings and results of an original research i n the field of mining engineering; review articles, which assess, evaluates, and interprets the findings of a comprehensive review of sufficient number of scientific articles and summarize them at present information and technology level; technical notes, which may be defined as a short article that describes a novel methodology o r technique; a case studies, which are based on the theoretical o r real professional practice and involves systematic data collection and analysis.
