Quartz vein type gold ore processing technology is mainly cyanidation and flotation. The determination of the technology mainly depends on the size of the gold grain and the symbiotic relationship with other minerals. In case the mineral surface is contaminated or there is thin film free gold, the jigging separation can be used to recover some ...

What are the types of gold ore? Gold ore is categorized into two main types: lode deposits and placer deposits. Lode deposits are found in veins or rock formations, often deep underground. Placer deposits are formed by the erosion of gold from its original source and are found in riverbeds, beaches, or sedimentary environments, typically near ...

Determining the specimen's density is one of the first steps in recovering gold from gold ore. Knowing the density of the ore makes the process more effective. The density of gold ore varies from one type to the next. Typically, impure gold is around 16 to 18 times heavier than its associated host rock, which has a density of 2.5.

Ore deposits are often classified based on examples of their type, such as Broken Hill-type lead-zinc-silver deposits, or Carlin-type gold deposits. Hydrothermal ore deposits are also classified according to the temperature of formation, which roughly correlates with particular mineralizing fluids, mineral associations, and structural styles.
