Identify gold ore deposits by the locations Affected by the formation process and environment, there are many types of gold ore deposits. The common ones are as follows: epithermal deposits, orogenic belt deposits,

Hematite, also spelled haematite, heavy and relatively hard oxide mineral, ferric oxide (Fe2O3), constitutes the most important iron ore because of its high iron content (70%) and its abundance. Besides, hematite is also

Gold has always been one of the most popular metals in the world. The crazy gold rush makes it sought after by various gold mining companies, mineral experts, and amateur gold prospectors. So

Hematite, also spelled haematite, is a weakly magnetic iron ore with better floatability than magnetite and wide distribution. It is one of the most important raw materials for the extraction of iron. Its

According to industry statistics, each kilometer of highways and high-speed railways requires hundreds of thousands of tons of sand and gravel aggregates. The quality of some fine sand must meet the standards for

Gravity concentration can be defined as the process by which particles of different sizes, shapes, and densities are separated from each other by the force of gravity or the centrifugal force. Gravity concentration,

Why do we need the test work? Mineral testing allows you to get detailed information about the ore properties, which in turn provides more support and help for your later geological prospecting. The

1. What is flotation separation? Flotation separation mainly refers to froth flotation, which is based on the difference in physical and chemical properties of the surface of minerals, using the buoyancy of bubbles

Using flotation reagents correctly means choosing right reagent regime prior to the flotation process.  Reagent regime refers to a set of rules regulating the reagent type added, usual quantity fed, and the appropriate
