Minerals that are compounds of oxygen together with another element.
Group of minerals that are compounds of one or more metallic elements combined with oxygen, water, or hydroxyl (OH). The oxide group contains the greatest variations of physical properties. Some are hard, some soft. Some have a metallic luster, others are clear and transparent. The Oxide group is divided into the Simple Oxides, Hydroxides, Multiple Oxides
Copper ores that are generally amenable to leaching and contain such copper-bearing minerals as chrysocolla, malachite, azurite, and others. These oxidized ores frequently occur above primary, secondary, and mixed sulfide zones.
