The medium may be a dense liquid, a solution, or a finely ground material in suspension in water (heavy media). The process may static. It takes place in a drum or a tank. It may be dynamic. It is then effected in a cyclone. The lighter product is sometimes referred to as float, the heavier as sink. This is a gravity separation process.

Heavy Media Separations - OneMine. Heavy liquid separation is a mutation. The heavy media process is used extensively to clean coal and for the concentration of a wide variety of ores such as those of iron, lead-zinc, chrome, manganese, tin, tungsten, fluorspar, magnesite, sylvite, garnet, diamonds, gravel, etc.
HMS offers the following potential advantages:12 1) Ability to make sharp separations. 2) Ability to change the specific gravity of separation quickly to meet changing conditions. 3) Ability to remove products continuously. 4) Ability to treat a broad size range of products. 5) Ease of start-up and shutdown without loss of separating efficiency.
ABSTRACT Pre-concentration of lead and zinc ore in Calcimin (public Co) which is done using heavy-medium cyclones (HMC) undergoes lots of inefficiencies and not in the desired manner. Considering the fact that feed material is variable in the case of Zn–Pb grades, it is important to make HMC plant flexible when facing different ore types. The present study aims to prepare a …

Heavy media separation dates back to several centuries. Initially, a fine magnetite was used as a heavy media. In 1936, a plant was designed employing organic liquid as a heavy media for …
Heavy media drum separation HMS also known as dense media separation, is a process used to separate materials that have different specific weight. A heavy media fluid of the correct density is pumped and kept in circulation inside a rotating drum. The material to be separated is immersed into the fluid, which allows lighter particles to float

In heavy-media separation (also called sink-and-float separation), the medium used is a suspension in water of a finely ground heavy mineral (such as magnetite or arsenopyrite) or technical product (such as ferrosilicon). Such a suspension can simulate a fluid with a higher density than water.
