Which among the following is an alloy of antimony,tin and copper?

Give the correct order of initials $T$ or $F$ for following statements. Use $T$ if statement is true and $F$ if it is false.
$(i)$ $Cu$ metal is extracted from its sulphide ore by reduction of $Cu_2O$ with $FeS$.
$(ii)$ An ore of Tin containing $FeCrO_4$ is concentrated by magnetic separation method.
$(iii)$ Auto reduction process is used in the extraction of $Cu$ & $Hg$.
$(iv)$ Cassiterite and Rutile are oxide ores of the metals.

Which of the following statements is not correct?

For the following statements,mark $T$ for true and $F$ for false statement.
Statement $1$: $SnO_2 +$ wolframite,in this $SnO_2$ is magnetic while wolframite is non-magnetic in nature.
Statement $2$: Argentite ore is concentrated by froth floatation method.
Statement $3$: Copper and lead ores are reduced by self-reduction method.
Statement $4$: In metallurgy of $Fe$,$CO$ is used as a reducing agent at low temperature.

List-$I$ shows reactions involved in the metallurgy of $Pb$ (lead) and List-$II$ shows the names of the processes. Match List-$I$ with List-$II$ and select the correct code for your answer.

List-$I$	List-$II$
$(P) \ PbS + 2PbO \xrightarrow{\Delta} 3Pb + SO_2 \uparrow$	$(1) \ \text{Smelting}$
$(Q) \ PbS + \frac{3}{2}O_2 \xrightarrow{\Delta} PbO + SO_2 \uparrow$	$(2) \ \text{Self reduction}$
$(R) \ PbCO_3 \xrightarrow{\Delta} PbO + CO_2 \uparrow$	$(3) \ \text{Calcination}$
$(S) \ PbO + C \xrightarrow{\Delta} Pb + CO \uparrow$	$(4) \ \text{Roasting}$

Which of the following is correctly matched?
