Flux For Melting Copper
Copper processing copper processing roasting smelting and converting.
Flux for melting copper. Alucoflux yb melting cover for copper zinc alloys containing over 8 0 zinc. Assists with slag free casting by lowering the melting point and viscosity of the slag and allowing it to rise to the surface for skimming. They are used in both extractive metallurgy and metal joining. In metallurgy a flux derived from latin fluxus meaning flow is a chemical cleaning agent flowing agent or purifying agent.
Table of contentsgeneral fluxspecific fluxes or flux for specific casesfluxes generally used functionsscorification fluxes general flux in a laboratory where much work is done in a day and the class of ore is uniform what is called a general smelting flux may be made. It is manufactured by synex inc. Keeps melting unit clean. If the ore from which gold is to be separated out contains elements and impurities with a high melting point.
Some of the earliest known fluxes were sodium carbonate potash charcoal coke borax lime lead sulfide and certain minerals containing phosphorus. This does not include the manganese bronze alloys. Copper and chromium copper should be melted under a floating flux cover to prevent both oxidation and the pickup of hydrogen from moisture in the atmosphere. The conventional way of melting copper is through the use of large scale equipment for mass producing great quantities of copper such as induction furnaces and foundries.
Anhydrous borax boric acid assay dense soda ash assay silica fluorspar potassium carbonate manganese dioxide and more. With chromium copper the cover should be a proprietary flux made for this alloy. Fluoride containing gray and ductile iron ladle flux. For cleaning gray and ductile iron ladles.
In the case of copper crushed graphite should cover the melt. Bcs brass casting flux is a professional grade cover and drossing flux for use in brass bronze copper melting. We also have pre mixed standard refining flux hank chapman flux flux thinner and many more special recipes for all of your melting applications. In older processes the concentrate containing between 5 and 10 percent water is first roasted in a cylindrical refractory lined furnace of either the hearth or.
This flux is adapted to ores that may be classified as average but is so compounded as to allow the addition of. Reduces zinc loss reduces fuming. Some of our individual flux components include. Once a concentrate has been produced containing copper and other metals of value such as gold and silver the next step is to remove impurity elements.
Fluxes may have more than one function at a time. This flux reduces metal oxidation promotes separation of dross from metal and reduces gas levels in the melt. Alucoflux gb melting cover flux for copper and bronze alloys. The process becomes highly energy intensive as high temperatures are required to get the mixture melted down.
Generates a dry powdery dross cover. And sold to the foundry industry as ba 315 brass bronze flux.
