Question

pls answer this........​

Answer 1

the branch of science and technology concerned with the properties of metals and their production and

the technique or science of separating metals from their ores.

Answer 2

Answer:

1)the technique or science of working or heating metals so as to give them certain desired shapes or properties. the technique or science of making and compounding alloys. the technique or science of separating metals from their ores.

2)The gangue particles are the unwanted materials or impurities like sulfide, oximdes, silica sand etc which are mixed in minerals and which are removed during extraction of pure metals.

3)Metallurgy consists of three general steps: (1) mining the ore, (2) separating and concentrating the metal or the metal-containing compound, and (3) reducing the ore to the metal. Additional processes are sometimes required to improve the mechanical properties of the metal or increase its purity.

4)What is the Reactivity Series?

The reactivity series of metals, also known as the activity series, refers to the arrangement of metals in the descending order of their reactivities.

The data provided by the reactivity series can be used to predict whether a metal can displace another in a single displacement reaction. It can also be used to obtain information on the reactivity of metals towards water and acids.

5)The primary use of iron ore is in the production of iron. Most of the iron produced is then used to make steel. Steel is used to make automobiles, locomotives, ships, beams used in buildings, furniture, paper clips, tools, reinforcing rods for concrete, bicycles, and thousands of other items.

i think it's correct

if it is
