Foundry sand is high quality silica sand used as a casting material in metal casting industry. Used foundry sand can contain a range of chemicals, as a result of the metals cast and the binding agents used. If placed in landfill there is a risk that these chemicals can leach into the environment.
Millions of tons of foundry sand waste are generated each year, with only a small percentage of this waste being recycled. While a low percentage of this waste may be hazardous, most of the foundry sand waste could be recycled or reused for a number of other purposes. FOUNDRY SAND RECYCLING

Recycling sand. Reducing and recycling scrap. Managing emissions. Recycling sand. Recycling sand is an area in which we have made significant investments. We know the positive impact that managing sand can have on the environment but we are also very conscious, that if not done properly, it can have a negative impact on the quality of a product.
Foundry operations are reasonably basic, you can use use a timber or metal pattern to produce a cavity in a two-part sand mold, then properly pour molten metal into the mold cavity. The more you practice metal casting, the better your skills – work and creativity will become.
The flowsheet shown in this study is particularly adapted to the requirements of the average foundry to reclaim foundry sand for re-use. Any foundry whose new sand delivered costs is too high should seriously consider reclamation with the flowsheet as illustrated. This reclaimed sand is usually equal to, or better than the original sand.

The Cast Metals Federation works to foster development, collaboration and innovation in the UK Casting Industry to promote good practice and represent the Best of British casting across the globe.
The cost to the UK foundry industry to purchase new sand and subsequently dispose it to landfills is considerable (especially after the introduction of UK landfill tax: £84.40/t and £2.65/t for active and non-active waste respectively), which affects turnover.
Casting of sand is the simplest and most versatile of all casting methods used to produce castings. There are various types of sand used in casting. These different types of casting sand have their own advantages and disadvantages. The type of metal required to be cast influences, which additives and what gradation of sand is used. Types
Nov 23, 2011· Green sand is alot more fragile then oil bonded sand. If you are looking for amazing finishing on your casting use oil bonded sand.

Recycling foundry sand. The recycling of non-hazardous, spent foundry sand can save energy, reduce the need to mine materials and may reduce costs for both producers and end users of foundry sand. Recycled foundry sand typically finds use in construction applications but can also be used in the following ways:
Currently, most of the waste foundry sand (WFS) generated in the UK and many parts of the world are sent to landfill. The rising cost of land-filling and the associated environmental problems have prompted the metal casting industry into reusing the WFS.
From Eaton Hall quarry near Congleton, Cheshire, Tarmac supplies high quality sub-rounded silica sand suitable for a wide range of industrial uses.

Sand casting is one of the few available processes for metals with high melting temperatures such as steels, nickel, and titanium. Because of its flexibility, heat resistance, and relatively low cost, sand casting is the most widely used casting process. Castings are produced by …
Sand casting. Sand castings are created by packing a fine sand mixture around a pattern of the desired product. The pattern is slightly larger than the final product to allow for shrinkage of the aluminum while cooling. Sand casting is economical because the sand can be reused multiple times.
UK Aluminium Industry Fact Sheet 5 : Aluminium Recycling 2 The Product Secondary aluminium refiners convert most of their materials into foundry ingot, generally based on the aluminium-silicon alloy system, with additions of other metals such as copper and magnesium. These ingots, to BS EN 1676 or …
recycling spent foundry sand is dependent upon economics - the bottom line issues will be cost, availability of supply, and consistent quality of the feedstock.
The sand is reused until it is physically degraded, at which point it is removed from the sand supply. Foundry slag is composed of fluxing agents and impurities removed from the molten metal prior to casting. Most foundry sands, as well as ferrous foundry slags, can be used as fine or coarse aggregates in construction and soil applications.
