9 Ore Deposits and Economic Minerals – Mineralogy

Many different mineral commodities are important to modern society However, when mineralogists think about mining, they are generally thinking of ore minerals that are the sources of important metals, or of minerals that have specific, highly valued properties (eg, asbestos, micas, potash, and gems of all sorts)That is what we will focus on in most of the rest of this ore sources Outcomes from reconciliation studies may be put into two categories; misclassification of significant tonnages of ore grade material (common), and discovery of problems in postmining processing and documentation (less common) A definite consequence of the former is the haulage of misclassified ore to waste dumps or waste to the Ore Grade Reconciliation Techniques – A Review Mining ôÿ f¤¨ýp3’•Z ª31Æ ýñëÏ¿ Žë±ÎûÏêÿýó¥¨ÓØn X€Mb\ºwšÓä­iÆ#Ð ä ‰JÂK\ߟU¿ÚLQ ¤ÑÓ ¨îš4¤ g1I:dºa÷®K¶e[à×Y \¾ jýÿûçë\¶ú tPi$6Ój¶µl“A ­1ð„l'SÌoo ¢ûxwY%e;³ obNw f¨ÿÞ÷Ó2§YyŸ9“ Ë p×G2™ JIrÌ ¾ ºÑ lÐ@#H Ý COREMill Mill Grain Software Solutions CORE Tech2014年6月5日  The broken ore density (BOD), commonly related to the swell or bulking factor, is an important parameter for block caving design It is well known that the ore column density decreases (and swell (PDF) Assessment of broken ore density variations in a
