Extracting ores Mining of mineral resources Siyavula

Once the ore is on the surface, the process of getting the mineral you want out of the rock can start. Once the mineral is separated from the rest of the rock, the mineral needs to be cleaned so that it can be used. This process can be represented by the following flowchart diagram: In this chapter we will look at each of the steps in more detail.

Metal Extraction Process for High Grade Stibnite of Kharan ...

gangue minerals which are often pyrite, sphalrite, calcite, barite and other clay e mineral [1]. Such ores are usually up-graded by froth-flotation process [3] while high grade ores can be utilized directly for metal recovery due to substantial de-crease in gangue content. Antimony is usually extracted from its ores by either hydro-metallurgical or

Metal Extraction Process for High Grade Stibnite of Kharan ...

A rapid and simple process has been developed for the recovery of antimony metal from stibnite ore of Kharan area (Balochistan) of Pakistan. The ore was characterized by X-ray diffraction (XRD) technique and found to contain 66% stibnite i.e. antimony sulfide (Sb2S3). The process parameters for the extraction of antimony were optimized on laboratory scale by varying reaction temperature from ...

Mineral Extraction - an overview ScienceDirect Topics

Mineral extraction sites, which include strip mines, quarries, and underground mines, contribute to surface water and groundwater pollution, erosion, and sedimentation (see Chapter 14). The mining process involves the excavation of large amounts of waste rock in order to remove the desired mineral ore (Fig. 12.6). The ore is then crushed into ...

Introduction to Mineral Processing or Beneficiation

Jan 12, 2018  The unit value of this class of minerals is low but the purity is high, approaching a chemical grade. The minerals in this class are used directly for industrial applications once they are separated from a gangue content that must be low to start with. The low unit value only allows for marginal treatment costs.

The capital and operational costs are also lower than the other processes. However, unlike the other processes, this process cannot produce desalinated clean water and, thus need to be combined with MDC or RO. The revenue obtained comes only from the extracted minerals. The process is profitable only for the extraction of high value minerals. 6.

The grade or concentration of an ore mineral, or metal, as well as its form of occurrence, will directly affect the costs associated with mining it. The cost of extraction must be weighed against the metal value contained in the rock to determine which ores should be processed and which ores are of too low a grade to be worth mining.
