Oct 27, 2010 Acomparative analysis is made of magnetic separators used to decrease and stabilize the iron content in quartz sand. It is shown that obsolete electromagnetic roll and rotor separators are cumbersome, unreliable, and expensive to operate. The construction of belt roll separators using permanent magnets has a number of irremovable defects that impede the use of such separators in.
Contact For PriceIt is shown that the use of magnetic enrichment of quartz sand from a local deposit has a positive effect on the technological processes of glassmaking, and the use of specialized magnetic holder.
Read MoreFeb 14, 1989 The invention relates to a method of purifying quartz sand in order to remove gas nuclei and impurities. In particular iron and iron compounds are removed by causing the sand to react with at least hydrofluoric acid, in which method the quartz sand is preferably first cleared of free impurities, for example, by means of a flotation process which is known per se or by means of.

The mineralogy and properties of Northland's coastal sand deposits are of economic importance since 75 000t of quartz sand with 90 96 quartz is dredged annually from the northern east coast of the Aupouri Peninsula (Schofield 1970 Isaac 1996). STUDY AREA The Aupouri Peninsula is a Pleistocene tombolo, which.

Read MoreStarting from pegmatitic sand, the invention provides a method of purifying quartz sand, in which the amount of iron is reduced to less than 0.3 ppm, the amount of zircon to less than 1 ppm, and the amount of phosphor to less than 0.2 ppm. Gas nuclei are also removed. The method is carried out by washing with solution which contains at least 15 by weight of HF in water until at least 40 by.
Read MoreSep 01, 2007 The dominance of plutonic quartz in the medium to coarse sand fraction also points toward a crystalline source. However, the remnants of inherited quartz cement overgrowth around some of these grains indicate that at least 10–15 quartz grains were recycled from sedimentary rocks (e.g. the Cambrian Poughquag Quartzite etc.).
