Give the correct order of initials $T$ or $F$ for following statements. Use $T$ if statement is true and $F$ if it is false.
$(i)$ Every mineral is an ore but every ore is not a mineral.
$(ii)$ Slag is a product formed during the extraction of metal by the combination of flux and impurities.
$(iii)$ Highly pure metals can be obtained by zone refining.
$(iv)$ Carnallite is an ore of magnesium and sodium.

In the reaction,$P_2O_5 + 3CaO \to Ca_3(PO_4)_2$,$P_2O_5$ acts as......

In the Ellingham diagram,the plot is drawn between:

Match the following processes in List-$I$ with their respective applications in List-$II$:

List-$I$	List-$II$
$A$. Van Arkel method	$P$. Purification of titanium
$B$. Solvay process	$Q$. Manufacture of $Na_2CO_3$
$C$. Bassemerisation	$S$. Reduction of copper
$D$. Hall-Herault process	$R$. Reduction of aluminium

The alloy,which contains $95 \%$ aluminium and small amounts of copper,magnesium and manganese is . . . . . .

Consider the following statements:
$(a)$ When the lead-silver alloy is rich in silver,lead is removed by the cupellation process.
$(b)$ Froth flotation can be applied for non-sulphide ores also using a suitable activator.
$(c)$ $PbSO_4 + H_2SO_4$ electrolyte is used for the refining of $Pb$ by electrolysis.
$(d)$ Any metal will not reduce the oxide of other metals which lie above it in the Ellingham diagram.
Using $'T'$ for true and $'F'$ for false statements in the given sequence,select the correct set of code.
