II. IMPORTANCE OF MINERALOGY IN MINERAL PROCESSING

From mineral processing point of view, it is important to identify the ore and gangue minerals (mineralogical study), their textural relationship (grain size, grain boundary relationship etc.). The mineralogical study also helps in the modal distribution of ore and gangue minerals which decides the grade of ore.

Mineral processing - Wikipedia

Mineral processing can involve four general types of unit operation: comminution – particle size reduction; sizing – separation of particle sizes by screening or classification; concentration by taking advantage of physical and surface chemical properties; and dewatering – solid/liquid separation. In all of these processes, the most important considerations are the economics of the processes, which is dictated by the grade and recovery of the final product. To do this, the mineralogy of the ore needs to be considered as this dictates the amount of liberation required and the processes that can occur. The smalle

How do we extract minerals? - USGS.gov

Large tabular-shaped ore bodies or ore bodies lying more than 1,000 feet (300 m) below the surface are generally mined underground as well. The rock is drilled and blasted, then moved to the surface by truck, belt conveyor, or elevator. Once at the surface, the material is sent to a mill to separate the ore

Crusher is the important role in the investment and production cost of ore dressing plant. Therefore, the basic task of ore crushing operation is to supply proper material for the beneficiation. Whether the crushing process is good or not directly influences the technical and economic data.

Extractive Metallurgy | Introduction to Chemistry

Ore bodies are formed by a variety of geological processes. The process of ore formation is called ore genesis. Ore Preparation. It takes multiple steps to extract the “important” element from the ore: First, the ore must be separated from unwanted rocks. Then, the minerals need to be separated out of the ore

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 (e.g., asbestos, micas, potash, and gems of all sorts).That is what we will focus on in most of the rest of this chapter.
