Statement (i): Cu metal is extracted from its sulphide ore by reduction of Cu2O with FeS.
The given statement is False (F). Cu metal is not extracted from its sulphide ore by reduction of Cu2O with FeS. Instead, copper metal is extracted from its sulphide ore, copper pyrite (CuFeS2), by the following steps:
1. Concentration: The ore is concentrated by froth floatation process.
2. Roasting: The concentrated ore is heated strongly in the presence of excess air to convert copper sulphide into copper oxide.
2CuFeS2 + 4O2 → 2Cu2S + 2FeO + 4SO2
3. Smelting: The roasted ore is then mixed with silica (SiO2) and heated in a blast furnace. The following reactions take place:
Cu2S + FeO + SiO2 → Cu2O + FeS + SO2
Cu2O + FeS → 2Cu + FeS
The molten copper obtained is called blister copper, which contains impurities of Fe, S, and other metals.
4. Refining: The blister copper is further purified by electrolytic refining to obtain pure copper.
Statement (ii): An ore of Tin containing FeCrO4 is concentrated by magnetic separation method.
The given statement is True (T). An ore of tin containing FeCrO4 can be concentrated by the magnetic separation method. In this method, the powdered ore is passed over a conveyor belt that moves over a magnetic roller. The magnetic roller attracts the magnetic particles (FeCrO4) and separates them from the non-magnetic particles (tin ore). This process helps in the concentration of tin ore.
Statement (iii): Auto reduction process is used in the extraction of Cu and Hg.
The given statement is True (T). Auto reduction process is used in the extraction of copper (Cu) and mercury (Hg). In this process, the metal oxide is reduced to the metal by heating it in the absence of air or by using a reducing agent. For example, in the extraction of copper, copper oxide (CuO) is reduced to copper (Cu) by heating it in a blast furnace in the absence of air.
Statement (iv): Cassiterite and Rutile are oxide ores of the metals.
The given statement is True (T). Cassiterite (SnO2) is the ore of tin (Sn), and rutile (TiO2) is the ore of titanium (Ti). Both cassiterite and rutile are oxide ores of the respective metals. These ores are processed to extract tin and titanium metals through various extraction methods.
The given statement is False (F). Cu metal is not extracted from its sulphide ore by reduction of Cu2O with FeS. Instead, copper metal is extracted from its sulphide ore, copper pyrite (CuFeS2), by the following steps:
1. Concentration: The ore is concentrated by froth floatation process.
2. Roasting: The concentrated ore is heated strongly in the presence of excess air to convert copper sulphide into copper oxide.

The magnetic roller attracts the magnetic particles (FeCrO4) and separates them from the non-magnetic particles (tin ore). This process helps in the concentration of tin ore.

In this process, the metal oxide is reduced to the metal by heating it in the absence of air or by using a reducing agent. For example, in the extraction of copper, copper oxide (CuO) is reduced to copper (Cu) by heating it in a blast furnace in the absence of air.

The given statement is True (T). Cassiterite (SnO2) is the ore of tin (Sn), and rutile (TiO2) is the ore of titanium (Ti). Both cassiterite and rutile are oxide ores of the respective metals. These ores are processed to extract tin and titanium metals through various extraction methods.
