Land reclamation can be achieved with a number of different methods. The most simple method involves filling the area with large amounts of heavy rock and/or cement, then filling with clay and dirt until the desired height is reached. The process is called "infilling" and the material used to fill the space is generally called "infill".

Sand tailings fill reclamation. Sand separated from the phosphate ore – referred to as sand tailings – is returned to the mined area and used to fill the mine cuts to a specific elevation. Once pumping is complete, the soil that was moved during the mining process is placed over the sand tailings to match the elevations in the reclamation plan.

A carbohydrate is added to sand, which has been used to make foundry moulds or cores, and which has been bonded using an alkaline resol phenol-formaldehyde resin, prior to reclamation of the sand by a thermal reclamation. The thermal reclamation may be done in other equipment, for example, a rotary thermal reclamation unit, but is preferably done in a fluidized bed reclamation unit.
Sand Reclamation can be termed as the process of reconditioning of used sand in a foundry without lowering its original properties, which are particularly required for foundry application. Reclamation process for foundry sand is broadly of two types – Mechanical (Attrition) and Thermal. Thermal Reclamation is the process
During the reclamation process samples of the reclaim were taken for testing ignition losses in order to determine the process efficiency. The correctness of the assumed method of selecting the temperature range of the thermal reclamation of spent moulding sand …
Land reclamation is the idea of getting new land.It is usually done in coastal areas. Sometimes it is also done in areas like rivers and lakes.Usually, there is a natural process which fills such areas with sand, dirt and other materials. Land reclamation uses the same process, which is sped up.
Sep 11, 2001· In another thermal reclamation process the thermal treatment is done in a furnace having a fluidised bed, and the used sand which is fed to the furnace is first subjected to an attrition process so as to break down agglomerates into individual particles. A thermal reclamation process which utilises a fluidised bed is described in GB-A-2244939.
The Nobake Process Nobake is a casting process that involves the use of chemical binders to bond the molding sand. Sand is conveyed to the mold fill station in preparation for filling of the mold. A mixer is used to blend the sand with the chemical binder and catalyst. As the sand exits the mixer, the binder begins the chemical process of hardening.
Used in the VELOSET Sand Reclamation Process, they provide the only ester silicate process in which the sand can be reclaimed by a simple dry attrition process and reused at high levels equal to those typical of resin bonded sands. Additions: There are three grades of VELOSET hardener.

While process and economic variables dictate reclamation feasibility, some firms are saving money on their total sand costs. While you hear many things about spent foundry sand reclamation, one that comes up often is "if you don't do it now, chances are you will have to in the next few years."
A PLC is used to control all critical mixer timing functions to ensure usable first and last sand. Air Jets: – All BE mixers feature easily removable resin delivery jets. Using the Flow Control, the operator can easily calibrate at the actual point of resin entry, not a remote ball valve as others do.
The results of the efficiency of the primary reclamation process as well as the influence of the used sand temperature and other process parameters on it are presented in this paper. A separate stand realized on a reduced scale was built, which is an analogous process of the primary reclamation treatment of spent foundry sands.
Land reclamation in Singapore also allows for the preservation of local historic and cultural communities, as building pressures are reduced by the addition of reclaimed land. Land reclamation has been used in Singapore since the early 19th century, extensively so in this last half-century in response to the city-state's rapid economic growth.
United States. Sand casting foundries use approximately 5-10% of their total energy on sand handling processes. By adding a secondary sand reclamation process, foundries can expect to become more energy efficient as well as reducing solid waste from the foundry. To measure the broader environmental impacts, life cycle assessment (LCA) can be used.
