Smelting Technology of Metal Titanium and

Cold hearth Melting. Cold hearth melting uses a plasma (Plasma Arc) or an electron beam (Electron Beam) as a heat source, and can be divided into two processes of plasma cold bed furnace and electron beam cold bed furnace smelting. Electron beam coldhearth melting has many advantages over vacuum arc melting:

Hydrogen Plasma Smelting Reduction of Fe 2

The paper reports successful smelting reduction of iron ore (hematite) in thermal hydrogen plasma. A specially designed reactor with water cooled copper crucible and a plasma torch was used to demonstrate the process in 1kg scale. The number of stoichiometric requirement of hydrogen is a better parameter, instead of time, for determining the rate of the process.

gold processing furnace

Apr 24, 2017· The first step in the gold smelting process occurs when ore containing gold is mined from the earth. At this point, the crude binding matter and the gold metal need to be separated. This is accomplished by pulverizing or crushing the gold ore, and then placing it in a furnace. Read More

PLASMA ARC FURNACE Thermopedia

The main advantage of a plasma furnace in comparison with a usual blast cupola is in that the plasma furnace does not need intensive air blasts to support the burning process. Besides in the case of gray cast iron smelting in a plasma furnace, the consumption of electric power and the charge decrease.

Plasma arc waste recycling A simple introduction

Artwork: Although plasma recycling processes vary, most work in broadly this way. Raw waste is processed to remove any recyclable materials before being fed, with gas, to the plasma arc. This vaporizes the waste to produce syngas (which has to be scrubbed clean) and aggregate. Plasma arc recycling doesn''t involve combustion.

Microwave Gold Processing Kiln Kit Gold

First of all, you must have gold or silver in your concentrates to begin with and the more of it the better. The microwave gold smelting kiln is a tool for smelting only. It does not separate out the precious metals that are in your concentrates. You still need to have your end product called "buttons" assayed to determine its purity and content.
