Such ores are usually up graded by froth flotation process while high grade ores can be utilized directly for metal recovery due to substantial decrease in gangue content. Antimony is usually extracted from its ores by either hydro metallurgical or pyro metallurgical processes.

The primary methods used to extract minerals from the ground are: Underground miningSurface miningPlacer mining The location and shape of the deposit, strength of the rock, ore grade, mining costs, and current market price of the commodity are some of the determining factors for selecting which mining method to use.
Mineral extraction sites, which include strip mines, quarries, and underground mines, contribute to surface and groundwater pollution, erosion, and sedimentation. The mining process involves the excavation of large amounts of waste rock to remove the desired mineral ore.
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.
Similarly, when the metal price drops, the maximum grade is targeted to minimize extraction costs. If the ore that is charging into the furnace is a low metal grade, the extraction costs are high, and then the investment return is low. For example, the plot below shows the concentrate grade versus net smelter return.
On Earth, system improves ore content at the extraction point, using patented mineral electrostatic beneficiation equipment, to improve ore to waste ratio in the high 90%, plus system remediates contaminated ground wastewater electrolysis into green hydrogen.
