Sand Sand Additives SILICA SANDS. We stock a wide variety of subangular and round grain sands available in both 50# and 100# bags along with 4000# palletainers. Round Grain sand has a reduced surface area, which significantly reduces the necessary bon or binder needed in green sand and nobake systems. FAIRMOUNT MINERALS WEDRON SILICA
Chromite sand is sometimes used as facing sand, whereby quartz sand is used as filler sand but also as a mold material for core production. Consequently, in addition to quartz sand and binder residues, the accumulating used sand also contains valuable chromite sand which is to be reclaimed during used sand conditioning.
Based on type, the global chromite market can be segmented into high chromium chromite, high iron chromite, and high aluminum chromite. Based on application, the global chromite market can be segregated into stainless steel, chemicals, pigments, refractories, and foundry sand.
Pure chromite sand and its chromitebased moulding sand prepared with use of sodium silicate were subjected to heating within 100 to 1200 °C. After coolingdown, changes of base grains under thermal action were determined. Chromite moulding sand was prepared with use of wt% of domestic made, unmodified sodium silicate (waterglass) grade 145.

CHROMITE SAND FOUNDRY GRADE. Foundry grade CHROMITE sands are not only used as casting sands in cores and moulds in steel and iron foundries, but also as base material in sliding gate mixes or plugging sands in ladles at steelworks. Plomp Mineral Services' foundry grade chromite sand, origination from South Africa, is world famous for its excellent characteristics:
From October 1, 2011, specialty chemicals company LANXESS will market its foundrygrade chromite sand to customers around the world direct from its own chrome ore mine in Rustenburg, South Africa. LANXESS is already among the world's top producers of chrome ore for chemical applications.
refractory is left on the sand surface. This layer or barrier can prevent or minimize the penetration of molten metal into the sand, can reduce or prevent "burnon" and erosion of the sand and generally improves the quality of a casting surface. The benefits of a foundry coating are only achieved if the coating is the proper one for the job and
