Question

In the extraction of copper, its sulphide ore is heated in a reverberatory furnace after mixing with silica to: (A) remove FeO as FeSiO 3 (B) separate CuO as CuSiO 3 (C) decrease the temperature needed for roasting of Cu 2 S (D) remove calcium as CaSiO 3

The copper ore contains iron, it is mixed with silica before heating in reverberatory furnace. FeO slags off as FeSiO 3. FeO + SiO 2 longrightarrow FeSiO 3

Q. In the extraction of copper, its sulphide ore is heated in a reverberatory furnace after mixing with silica to:

remove $F e O$ as $F e S i O_{3}$

separate $C u O$ as $C u S i O_{3}$

decrease the temperature needed for roasting of $C u_{2} S$

remove calcium as $C a S i O_{3}$

The copper ore contains iron, it is mixed with silica before heating in reverberatory furnace. $F e O$ slags off as $F e S i O_{3}$ .
$F e O + S i O_{2} ⟶ F e S i O_{3}$

Q. In the extraction of copper, its sulphide ore is heated in a reverberatory furnace after mixing with silica to:

remove FeO as FeSiO3​

separate CuO as CuSiO3​

decrease the temperature needed for roasting of Cu2​S

remove calcium as CaSiO3​

The copper ore contains iron, it is mixed with silica before heating in reverberatory furnace. FeO slags off as FeSiO3​. FeO+SiO2​⟶FeSiO3​

remove $F e O$ as $F e S i O_{3}$

separate $C u O$ as $C u S i O_{3}$

decrease the temperature needed for roasting of $C u_{2} S$

remove calcium as $C a S i O_{3}$

The copper ore contains iron, it is mixed with silica before heating in reverberatory furnace. $F e O$ slags off as $F e S i O_{3}$ .
$F e O + S i O_{2} ⟶ F e S i O_{3}$
