Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore. Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and

For over 30 years, PHOENIX Process Equipment has been committed to producing the most efficient and reliable technology for tailings dewatering, liquid solid separation, fine particle wet classification and separation, slurry and sludge thickening, effluent water treatment, and water purification and water recycling.
Mineral processing can involve four general types of unit operation: comminution particle size reduction; sizing separation of particle sizes by screening or classification; concentration by taking advantage of physical and surface chemical properties; and dewatering solid/liquid separation. In all of these processes, the most
Process. The 16th century process of separating copper and silver using liquation, described by Georg Agricola in his 1556 treatise De re metallica, remained almost unchanged until the 19th century when it was replaced by cheaper and more efficient processes such as sulphatization and eventually electrolytic methods.
Gold cyanidation (also known as the cyanide process or the MacArthur-Forrest process) is a hydrometallurgical technique for extracting gold from low-grade ore by converting the gold to a water-soluble coordination complex.It is the most commonly used leaching process for gold extraction.. Production of reagents for mineral processing to recover gold, copper, zinc and

Tungsten Extraction Process Summarized. The ability to recover a high-grade concentrate from an initial coarse unclassified feed, with a minimum amount of slimes, is one of the outstanding features of this flowsheet. Special consideration is given to the friable nature of the tungsten by using Crushing Rolls and the quick pass grinding offered

Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source,
Process overview. Outotec Dry Tailings Plant product consist of thickening, filtering and dry material handling processes. A Thickener Plant will dewater the tailings from very low solids density to medium and high density. As an example from 5 % w/w solids up to around 65 to 70 % w/w solids for an iron ore tailings. The Thickened Tailings
This process uses starch (depressant) and amine (quartz collector) as reagents to promote the separation of the contaminant mineral (quartz) from the iron-bearing mineral. The floated material from the flotation process is also sent to the tailings thickener. The underflow from the flotation process is sent to the concentrate thickener.
Metallurgical processes need to know the metallic content of the different products obtained in recovery and refining processes. If we have to know about gold assay, it is important to mention the Fire Assay Process that has been employed in the mining industry for a long time. Basically the ore is mixed with a mixture of fluxes and during the

The Sylvinite ores mined in conventional mines contain Sylvite (20 to 30% K2O), Halite, sometimes Carnallite and 1 to 5% insol. Liberation, in some cases, is substantial at 1 cm (3/8 inch), and virtually complete in all cases at 14 mesh. The separation processes include dissolution of the Carnallite, and removal of the insols, followed by mechanical separation of Sylvite from the Halite.
Refining the ore. Ore is trucked from the open pit to the processing plant where it goes through three stages of crushing and screening, pre-concentration via heavy media separation followed by flotation, oxidative leaching and dewatering.

Operations Strategy Process existing surface mineralised materials and tailings followed by development of below ground
The residue is pumped into land based ponds where naturally impervious layers or sealants minimise seepage. The residue is typically deposited as a dilute slurry, with the solids settling and consolidating over time and the surface water collected for return to the refining process. The design, construction and operation of these storage dams
Mineral Refining Company (MRC) has developed an innovative, patented process to economically recover micron-sized coal and minerals that are currently disposed of as waste. Minerals processing has historically used mechanical separation techniques and flotation to separate impurities from valuable minerals. These techniques are effective for

Tailings generally contain small amounts of the valuable mineral(s) not completely recovered during beneficiation ; some unwanted or undesirable deleterious minerals ; and some of the chemicals that may have been used in the course of the separation process. Underground mines may use these tailings to backfill mining-created underground voids.
Alfa Laval has a range of robust equipment and knowhow to optimize key processes in mineral beneficiation, extraction and tailings dewatering. Visit us today and explore how we can help you boost capacity, save space, raise yields and ensure operational safety.
