Amongst the following ores, the total number of oxide ores are :

Siderite, Magnetite, Haematite, Malachite, Zincite, Cuprite

Iron oxide, which has equal proportions of iron(II) and iron, is the mineral magnetite's main constituent (III).
Iron oxide, also known as hematite or haematite, is a heavy and difficult oxide mineral (${\mathrm{Fe}}_2{\mathrm{O}}_3$).
A zinc oxide ore is called zincite.
With the chemical formula ${\mathrm{Cu}}_2\mathrm{O}$, cuprite is a significant copper resource. The metal in question is copper (I) oxide, which is a kind of metal. Consequently, this ore is an oxide ore.

Magnetite, Haematite, Zincite, Cuprite.
