Certain mineral deposits are naturally occurring concentrations of minerals that can be economically extracted. These deposits can include metals like gold, silver, and copper, as well as non-metallic minerals such as limestone and gypsum. The formation of these deposits often occurs through geological processes like volcanic activity, sedimentation, or hydrothermal solutions. Mineral deposits are classified into various types based on their formation and composition. For example, placer deposits are formed by the accumulation of minerals in riverbeds, while vein deposits occur in fractures of rocks. Understanding these deposits is crucial for mining and resource management.
