I understand the carbon can be "ashed" in an electric muffle furnace (I don't have one) but assume a gas furnace or torch would create too much wind and either volatilize the microscopic gold particles and/or blow the particles and ash out of the vessel - hence the smelting question.
Furnace construction. l Energy,furnace chamber used Morgan materials imported fibers, high purity ceramicfiber insulation( energy saving 40% and weight . lighter about 50% than old furnace). l Big yield capacity and high productivity, especially used for. heating treatment of small or medium products. l Double layers carbon steel casing with
Standard Test Method for Determination of Carbon Black Content in Polyethylene Compounds By the Muffle-Furnace Technique1 This standard is issued under the ﬁxed designation D 4218; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision.
Pitch, and Manufactured Carbon and Graphite) Ash is assessed by gravimetric loss. A low-walled ceramic crucible is ignited at 800° C in a muffle furnace and cooled to room temperature in a desiccator. A sample of 10 g of dry powder (accuracy 0.1 mg) is weighed in a low-walled ceramic crucible.
Battery 1700°C Vacuum Chamber Atmosphere Furnace for Silicon . With corrugated pipe, vacuum pump (connected to the furnace and vacuum tube), KF25 quick card sets, vacuum flapper valve, resistance vacuum gauge, etc., whereas the minimum vacuum degree is less than 5 pa, can also be hydrogen and argon, nitrogen, oxygen, carbon monoxide, protective gas such as ammonia decomposition gas, &energy

"Muffle Furnace" manufactured by International Equipment is a very compact laboratory furnace that can rise up to a temperature of 1000 degree Centigrade. These furnaces normally come with size 4 inch x 4 inch x 9 inch deep and 6 inch x 6 inch x 12 inches deep. Muffle furnace is used to check Ash percentage in polymers. The working is very
the muffle furnace at 900°C for 7 minutes. They were removed from the furnace, cooled in desiccators and reweighed. The loss in weight minus the amount of moisture equals the volatile matter. 2.2.4 Determination of the amount of fixed carbon . This was done by calculation( ASTM D 3172, 2002. The percentage moisture) (M), ash (A), and
M1700 muffle furnace consists of high quality alumina fiber brick and MoSi2 heating elements with special design, and can be used up to 1700 C. It is an ideal tool for materials annealing and sintering in your research laboratory. 1600℃ Muffle

Usually with either of these leaches you carry out filtration after the dissolution and any un-ashed carbon on the filter is sent for re-ashing. It is possible to ash carbon completely if the carbon layers in the furnace are kept shallow, around 10mm deep for CIP type carbon, 20mm deep for carbons which have only contacted solutions.
Also, advances in materials for heating elements, such as molybdenum disilicide offered in our 1600°C and 1700°C furnaces, can now produce working temperatures up to 1750 degrees Celsius, which facilitate more sophisticated metallurgical applications.
Description: KJ-V1700 Graphene vacuum furnace is widely used for heating treatment of metal materials in low vacuum, recursive, protective atmosphere, also can be used for heating treatment of special materials, such as carbonization process of carbon products. The furnace chamber is graphite felt with excellent thermal insulation function and
