Answers
Explanation:
1. Metallurgy is defined as a process that is used for the extraction of metals in their pure form. The compounds of metals mixed with soil, limestone, sand, and rocks are known as minerals. Metals are commercially extracted from minerals at low cost and minimum effort. These minerals are known as ores. 2. USES OF METALS AND NON-METALS
Uses of some common metals and non-metals are as follows. Metals Iron is used for making automobiles, machinery, pipes, containers, nails, etc. Gold and silver are used for making jewellery. Copper is used for making electrical wires, cooking utensils, etc. 3. a metal (e.g. gold, silver, or platinum) that resists chemical action, does not corrode, and is not easily attacked by acids.
Explanation:
Metallurgical Processes
Metallurgical engineering is a discipline concerned with extracting metals from their ores, and the development, production, and use of metallic materials. Metallurgical engineering is based on the principles of science and engineering and may be divided into process metallurgy, which is concerned with extracting metals from their ores to make refined alloys, and physical metallurgy, which involves the shaping, alloying, heat treatment, joining, corrosion protection and testing of metals
USES OF COMMON METALS AND NON METALS
USES OF COMMON METALS-Gold, Platinum, and silver are used as jewelry and ornaments.
Iron and steel are used for construction purposes.
Aluminum, the steel is used as utensils.
Mercury is used in thermometer and helps to check the temperature.
Aluminum is used as insulation wires.
NOBLE METALS
Abstract. Noble metals used for dental castings continue to consist of alloys of gold, palladium, and silver (not a noble metal), with smaller amounts of iridium, ruthenium, and platinum. The majority are used as a backing for ceramic baking, with the rest used as inlays, on lays, and unveneered crowns.
