I am currently using Borax, Silica flour, Soda ash and Potassium nitrate, the sludge contains also copper, I need a guideline on flux calculation to use in order to move the copper or any other Base metal to the slag. I would like to know more about flux calculation for gold smeltin
Low-temperature Smelting of Ilmenite in Borate Melts to Produce Pig Iron and Titania-containing Slag. Authors ... By the leaching-calcination option, the slag is first allowed to cool somewhat and is then crushed to minus 35 mesh and leached 2 h at 80 deg to 90 deg c to dissolve borates. This step upgrades the slag from 25 to 70-80 wt pct tio2.

Dec 12, 2017· Silico manganese is smelted with dolomite or calcite to increase the slag fluidity and at the same time also help reducing manganese oxide content from the slag. The slag on the other hand ranges between 1573 K and 1653 K as per its composition.
For fire assaying ores, usually fluxes, materials such as borax, soda, silica are added to the ore. The amounts of each chemical added to the flux mixture depends upon the elements present in the particular ore, such as sulfur and iron. Usually lead, in the form of Litharge, is also added.

Much of this material is used in the production of iron, steel, and other metals. Fluorspar can serve as a flux that removes impurities such as sulfur and phosphorous from molten metal and improves the fluidity of slag. Between 20 and 60 pounds of fluorspar is used for every ton of metal produced.
Oct 01, 2016· In the study, both borax and ground slag were used together as an additive in order to observe effects on the material characteristics of briquette samples. In this scope, compressive strength and bulk density of the samples produced using borax and ground slag were defined.
fluxes (p. 143). Considering that borax was a well-known flux in period, I think it's reasonable that it was used in the fusion step for smelting silver. 6 For sufficiently pure silver and gold in quartz, amalgamating with mercury was preferred over smelting.
The oxidized impurities (aided by Borax) will float up as slag and get collected. Therefore, the efficiency of the smelting process is highly increased and there is improved separation. The advantage of this is that a purer ingot will be gotten. ... There is less fluidity and it becomes very difficult to separate the slag from the pure molten ...

FLUORITE BARITE CLUSTER. A unique combo specimen of a Fluorite Barite Cluster. Beautiful golden Barite Crystals on amazing blue-green Fluorite. ... Fluorite is used as a flux when smelting metals to help the slag rise to the top and give better fluidity to the molten metal.
STOWAGE FACTORS, cbft/mt (1 cbm = 35.31 cbft) Information in the below columns is merely a guide and no substitute for checking accurate stowage factors from local. agents and/or shippers, or for inserting appropriate figures in contracts of carriage.
The most important of these is as a steelmaking slag flux, where the dolomitic lime replaces some of the quicklime (CaO) used in slag production. In addition to increasing slag fluidity, the presence of magnesia also helps to protect, and thus improve the life of, the steel vessel's refractory linings, which are made of magnesia.
The company is especially active in the field of minerals used in oil well drilling as Barite, ... Kiln Dust – Slag Cement ... Barite Bauxite Bentonite Borax Calcium carbonate Cement . A downdraft design is utilized to pull any dust .
Borax is a white crystalline mineral used in glass and ceramic enamel mixes. In the smelting process, borax helps to reduce the gold smelting point of the charge and capture metallic oxides. The addition of this reagent must be controlled; otherwise the slag will be extremely hard and non-homogeneous.
Dec 01, 2017· Others may come along with better advice, I crush or grind the slag glass to fine powder screen and pan, then I would melt the slag again this time, add a metal as a collector copper, or silver or lead, the slag crushed to powders and these metals could be mixed as filings, flakes beads or even as powders (like litharge PbO for lead) adding more flux, a little borax, sodium carbonate ...
FIELD OF INVENTION. The present invention relates to the ladle refining of steel with a surface slag covering. More specifically, the present invention relates to the utilization of solid, preferably briquetted, recycled ladle metallurgy furnace (LMF) slag as a flux in slag-making additions including desulfurizers, slag conditioners and synthetic slags.

• Making the slag more uid at the furnace operating temperature – reducing viscosity. Re ning of pure gold from bullion Bullion ingots are melted in clay crucibles under an anhydrous borax cover. Oxygen is passed through the metal which then forms oxides of the impurities. These oxides dissolve in the Dehybor cover and produce a uid borate ...
