· In fact, lead ore is a main source of silver and contributes substantially towards the world's total output. The most common lead ore is galena (PbS), which contains % lead. Other common varieties include cerussite (PbCO3) and angelsite (PbSO4). 4. Concentration • After the ore is removed from the mine, it is treated at a concentrating mill.

· Procedures for Metal Extraction. Concentration of Ores: Ores may be concentrated either by (i) Washing away the earthy materials in a stream of water in order to leave behind the heavier ores as is the case with tin ore or by (ii) Froth flotation where the ores are churned up with oil and water to form froth. This froth which contains the ore is skimmed off by blowing air.

Ores: The minerals from which a metal can be profitably extracted are called ores. Metals found at the bottom of reactivity series are least reactive and they are often found in nature in freestate; such as gold, silver, copper, etc. Copper and silver are also found in the form of sulphide and oxide ores.

How do we extract minerals? The primary methods used to extract minerals from the ground are: Underground mining. Surface (open pit) mining. Placer mining. The loion 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 ...
The extraction and isolation of metals from ores involve the following major steps: • Concentration of the ore, • converting ore into oxide • Reduction • Refining (Purifiion of the metal.) Concentration of the ore/ dressing or benefaction: The process of removal of the unwanted materials (, sand, clays, etc.) from the ore is
· In the stages involved in the extraction of metals in general – give reasons for the following. (i) Dressing of the ore is an essential process in the extraction of metal from its ore. Answer: The ores are found mixed with earthy impurities like sand, clay, lime stone etc. These unwanted impurities in .
Roasting is a process of heating a sulfide ore to a high temperature in presence of air. It is a step of the processing of certain specifically, roasting is a metallurgical process involving gas–solid reactions at elevated temperatures with the goal of purifying the metal component(s). Often before roasting, the ore has already been partially purified, by froth flotation.
Concentration or Dressing of the Ore Generally, the ores are found mixed with earthy impurities like sand, clay, lime stone etc. These unwanted impurities in the ore are called gangue or matrix. The process of removal of gangue from powdered ore is called concentration or ore dressing. There are several methods for concentrating the ores.
· What is the Process of Metallurgy The various steps used in metallurgy are listed below. 1. Enrichment or dressing of the ore 2. Conversion of the enriched ore into the oxide of metal 3. Extraction of metal from the metal oxide 4. Refining or purifiion of the metal Enrichment or dressing of an ore .
Downstream processing in pharmaceutical industries is very important because an ineffective downstream process can significantly increase the cost of the whole manufacturing process. Degerman et al. (2008) suggested that recovery and purifiion of solutes/products are the most expensive processes in pharmaceutical industries, and in some cases, its cost is higher than the whole bioprocess.
