Question:medium

Composition of siderite ore is

Show Hint

Ore composition knowledge is necessary for common extraction problems. Important ores to remember include: - Hematite ($\text{Fe}_2\text{O}_3$), Magnetite ($\text{Fe}_3\text{O}_4$), Siderite ($\text{FeCO}_3$). - Zinc Blende ($\text{ZnS}$), Calamine ($\text{ZnCO}_3$), Smithsonite ($\text{ZnCO}_3$). - Bauxite ($\text{Al}_2\text{O}_3 \cdot 2\text{H}_2\text{O}$).
