$S_{1} :$ In electrolytic refining, the impurities from the blister copper deposits anode mud which contains antimony, selenium, tellurium, silver, gold and platinum. (from copper pyrites)
$S_{2} :$ The low grade ore of copper is leached with acid and is then treated with scrap iron or $H_{2}$ to get copper.
$S_{3} :$ Siderite, curpite and argentite are oxide ores.
$S_{4} :$ Zone refining is very useful for producing semiconductor and other metals of very high purity, e.g., germanium, silicon, boron, gallium and indium.

Solution

The correct option is D T T F T
$S_{1}, S_{2}$ and $S_{4}$ are correct statements but in $S_{3}$ siderite $(F e C O_{3})$ is carbonate ore, curprite $(C u_{2} O)$ is oxide ore and argentite $(A g_{2} S)$ is sulphide ore. Hence, it is a wrong statement.
