Silver processing | Britannica

S.K. Haldar, in Platinum-Nickel-Chromium Deposits, 2017. 11.5.3.2 Smelting. Smelting is necessary to maximize the separation of the gangue (oxide and silicate) minerals from the sulfide minerals associated with the noble metals. Flotation concentrates undergo smelting and converting in a furnace at a temperature exceeding 1300°C to produce a silicate melt (slag) and an immiscible sulfide melt ...

Furnaces

After flotation separation, the concentrate would contain 1.7 percent silver, 10 to 15 percent lead, 10 to 15 percent copper, and 6 percent antimony. Approximately 25 percent of the silver produced comes from ores actually mined for their silver value; the other 75 percent comes from ores that have as their major metal value either lead ...

Lead processing | Britannica

The furnace column was but 18 in. deep, and again the endeavor was to volatilize as much lead and zinc as possible. The fumes, both from the blowing-up furnace and the blast furnace, were drawn away by a suction fan to be sent to a bag-house, one of the early installations of that apparatus.

Lead

Lead processing, preparation of the ore for use in various products. Lead (Pb) is one of the oldest metals known, being one of seven metals used in the ancient world (the others are gold, silver, copper, iron, tin, and mercury). Its low melting point of 327 °C (621 °F), coupled with its easy

The lead from the blast furnace, called lead bullion, then undergoes the drossing process. The bullion is agitated in kettles then cooled to degrees. This process results in molten lead and dross. Dross refers to the lead oxides, copper, antimony and other elements that float to the top of the lead. Dross is usually skimmed off and sent ...

12.3 Primary Copper Smelting

Flotation cells is widely applied for metal and non-metal separation processing from roughing, cleaning to scavenging. There are pneumatic &mechanically agitating flotation cells. Optionally, the floatation cell is able to suck ore pulp into the cell due to negative pressure created in the enclosed space in the propeller with a cover.

Melting Furnaces at Best Price in India

Feb 23, 2000· Although this is the third commercial Kivcet furnace to go into operation, the metallurgy at Trail is unique, because of the large proportion of zinc-plant residues that are treated in addition to lead concentrates and other lead-bearing materials. The non-symmetrical electrode layout leads to imbalances in the furnace reactance.

Float glass furnaces with a melting capacity of 700 t/24 h or more are an integral part of the pro-gramme, as is the smallest opal glass furnace for lighting ware, with a capacity of 1 t/24 h. Not only soda-lime glass, but also lead-free crystal, full lead crystal, opal and borosilicate glasses of differing compositions and water glass are ...

Electric Melt Furnace | Toledo Engineering Co., Inc.

The insides of these furnaces are lined with clay, blocks or bricks which protect the furnace's interior from heat, abrasion and oxidation. To melt the metal in the furnace, workers add layers of metal such as ferro alloys, limestone and coke. The limestone reacts with the metal, making the impurities float up to the surface of the melting metal.

Outotec Ausmelt TSL Furnace

Furnace turnaround. Furnace turnaround is the period between the completion of tapping and the furnace is ready for charging for the next heat. During this period, the electrodes and roof are raised and the furnace lining is inspected for refractory damage. If necessary, repairs are made to the hearth, slag line, tap hole and spout.

Floatation furnaces with floatation nozzle systems have been well proven for the heat treatment of Cu-strips and are now by far the most common design for con-tinuous annealing. Back in the 80s, strip floatation furnaces finally gained the victory against the former prevailing technology of vertical furnaces or catenary furnaces. WSP HExAR-Furnace
