Mineral dressing (= Orebeneficiation) The first process most ores undergo after they leave the mine is mineral dressing (processing), also called ore preparation, milling, and ore dressing or ore beneficiation. Ore dressing is a process of mechanically separating the
However, iron oxides such as magnetite and hematite are often associated with tin ores, so gravity separation is not possible. Therefore, magnetic separation and flotation methods will be used in tin ore dressing. Tin ore extraction process flow 1. Ore washing
The density of tin ore is bigger than paragenetic mineral, so we use gravity concentration to processing tin ore . Because there are many oxide iron ore inside, for example : magnetite, hematite, if use gravity concentration or flotation, that could not separate them from tin, so magnetic will be added is a high technological enterprise that integrated research, manufacture, sales ...

There are nine tin-bearing ores found naturally in the earth''s crust, but the only one that is mined to any extent is cassiterite. In addition to the ores themselves, several other materials are often used to process and refine tin. These include limestone
tin-based alloy in the smelting process. In China and else-where, many tin ores contain arsenic. As a result, tin-based alloy contains impurities from the tin making process10). Arsenic is widely distributed in the process of ore-dressing, tailings recovery and11,12)

Flotation, in mineral processing, method used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic condition—that is, the surfaces are either repelled or attracted by water. The flotation process was developed on a commercial
· Ore-dressing methods fall naturally into two general subdivisions— (1) concentration methods and (2) direct-recovery methods (amalgamation and leaching or wet methods). Concentration methods are employed to remove worthless gangue material and concentrate the valuable minerals of the crude ore in a smaller bulk.

concentration or dressing of the ore: the ore are usually obtained from the ground and therefore contained large amount of unwanted impurities, the elimination of these impurities from the ores is known as concentration. the concentration of it is done by the physical
The tin ore, having been crushed in the mills, was carried to the nearby dressing floors where water was used to separate the lighter wastes from the heavier cassiterite. The anonymous writer''s account of ''The Manner and Way of Dressing Tinn'' is the most complete contemporary description of the techniques employed (Anon., 1670, 2108-2111).

Abstract This paper surveys the growing divergence between the methods used for dressing lead and tin ores in Great Britain in the course of the nineteenth century. It is based as far as possible on archaeological and field evidence and the limitations of documentary evidence for the study of mineral dressing are considered. The passage of both lead and tin ore is traced from its emergence ...
Mineral processing art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock or gangue.
