Product Description
Fire Assay Cupellation Furnace for Gold Silver Precious Metal Testing
The Fire Assay Cupellation Furnace is designed for the cupellation stage of gold, silver and precious metal fire assay. After the fusion stage, the lead button containing precious metals is placed in a cupel and heated in the furnace for cupellation.
Key Features
- High Cupel Capacity
Available in 50, 100 and 168-cupel configurations for different laboratory throughput requirements. - Silicon Carbide Heating Elements
Silicon carbide heating rods are used as the furnace heating elements. - Temperature Monitoring & Control
Electronic temperature control with K-type or S-type thermocouple options. Rated temperature is 1000°C. - Pneumatic Door Operation
The furnace uses pneumatic door operation, with a recommended air pressure of 0.4-0.5 MPa. - Multiple Furnace Configurations
Three furnace chamber sizes and different electrical control configurations are available to suit different laboratory requirements.

Working Principle
After the fusion stage of fire assay, the resulting lead button containing precious metals is placed in a cupel and heated in the cupellation furnace. During cupellation, lead is oxidized and removed through the cupellation process, while the precious metals remain as a bead for subsequent weighing or analysis.
Applications
- Gold and silver fire assay laboratories
- Precious metal testing laboratories
- Mining and mineral testing laboratories
- Metallurgical and refining laboratories
How to Select the Right Configuration
The furnace can be selected according to the required cupel capacity and laboratory sample throughput:
- 50-Cupel Configuration - suitable for routine laboratory testing with relatively lower batch requirements.
- 100-Cupel Configuration - suitable for laboratories requiring medium batch capacity.
- 168-Cupel Configuration - suitable for higher-throughput fire assay laboratories.
For equipment selection and quotation, please provide your cupel specification, required samples per batch, daily sample throughput and available power supply.
Frequently Asked Questions
Q1: What is a fire assay cupellation furnace used for?
It is used for the cupellation stage of fire assay after sample fusion, helping separate the precious metals contained in the lead button for subsequent analysis.
Q2: What cupel capacities are available?
Three configurations are available: 50, 100 and 168 cupels per batch, using 6A, 7A or 7AS cupels according to the selected configuration.
Q3: What information should I provide for a quotation?
Please provide the required cupel specification, samples per batch, daily sample throughput and available power supply. This information helps us recommend a suitable furnace configuration.
