High Capacity 1200°C Fire Assay Fusion Furnace for Gold Assay Laboratory

Product Introduction

Designed for the fusion stage of routine and high-throughput fire assay, this Fire Assay Fusion Furnace provides multiple chamber configurations for laboratories with different sample processing requirements. Depending on the selected chamber and crucible size, the furnace can process multiple samples simultaneously, with capacity up to 42 samples per batch. Electronic temperature control, a pneumatic furnace door and an independent cordierite-mullite chamber support stable and convenient laboratory operation at temperatures up to 1200°C.

Key Features

Up to 42 Samples per Batch – Supports batch processing for higher-throughput fire assay laboratories.
• Four Chamber Configurations – Chamber sizes from 380×465×224 mm to 685×665×245 mm for different crucible and capacity requirements.
• Flexible Crucible Loading – Supports different crucible specifications and batch quantities.
• 1200°C Electronic Temperature Control – Provides controlled high-temperature conditions for fire assay fusion.
• Independent Cordierite-Mullite Chamber – Designed for long service life and convenient replacement.
• Pneumatic Furnace Door – Facilitates repeated crucible loading and unloading.
• Safety Protection – Leakage protection and automatic over-temperature alarm.

Suitable for the fusion stage of gold, silver and other precious-metal sample preparation.

Technical Specifications

Note: Loading capacity varies according to crucible specification. Additional configurations are available; final power requirements should be confirmed according to the selected furnace configuration.

Working Principle & Application

Prepared fire assay samples are mixed with the required flux, placed in crucibles and loaded into the furnace for high-temperature fusion.

The furnace is suitable for the fusion stage of fire assay in mining laboratories, mineral testing laboratories, metallurgical laboratories and precious metal assay laboratories.
