Ventilation for autoclaves assures that the various odors, steam moisture and low-levels of chemical vapors that come from the sterilization process do not escape further into the laboratory setting. When not regulated correctly with an adequate lab ventilation system, these vapors can pose serious health and safety concerns for lab personnel.

The gold is oxidized and dissolved as a salt. In this second, dissolution step, water, oxygen, and cyanide are added to the ore to transfer the gold from the solid phase to a water-based gold-cyanide complex. It's at this stage that Linde's dissolved gas management solution for gold extraction can really add value.
An autoclave is a pressure chamber used to sterilize equipment and supplies. It works by subjecting items to high-pressure saturated steam at 121°C (250°F) for about 15-20 minutes. This process ensures thorough sterilization of various tools and instruments, making autoclaves crucial in medical, laboratory, and food processing industries.

The aim of this present study was to use a combination of autoclave pre-treatment to eliminate epoxy resin, pre-extraction of industrial metals using FeCl 3 and HCl solutions, gold extraction using a KClO 3-HCl- CaCl 2 system, followed by gold recovery using hydroquinone to deliver a new, more efficient process for the recovery of gold from ...
Autoclaves are designed to harness the power of steam sterilization. The process primarily relies on three key factors: temperature, pressure, and time. Effective sterilization occurs when the steam temperature exceeds 250°F (121°C), and the autoclave should be pressurized to at least 20 psi. Additionally, the duration of the sterilization ...

The autoclaves operate at 1,725kPa pressure and 197°C to oxidize the pyrite (iron sulphide) into hematite (iron oxide) producing feed for the CIL circuits which recovers up to 95 per cent of the contained gold. Lime used to neutralize the acid generated in the autoclaves is produced from limestone quarried from a quarry 15km from the mine.
Autoclave HPAL is a challenging process requiring the toughest flow control solutions. Temperatures and pressures are extremely high, and acidic media and abrasive solids increase the wear and tear of the equipment. An optimal HPAL operation generally uses several different types of valves, such as slurry feed and discharge valves, pump ...
The usual procedure is to heat at 1.1 kilograms/square centimeter (kg/cm 2) [15 pounds/square inch (lb/in 2 )] steam pressure, which yields a temperature of 121°C. At 121°C, the time of autoclaving to achieve sterilization is generally considered to be 15-20 min, depending on the volume of the load.

pressure of 0.8-1.0 MPa. The advantages of this technology are due to the low cost of autoclave equipment and increased gold extraction. Besides, the relatively low temperature of autoclave leaching will favorably affect the extraction of gold in the hydrometallurgical cycle by reducing
Neutralized slurry from the pressure-oxidation circuit is pumped to two parallel streams of eight CIL tanks for gold extraction and subsequent recovery of gold in a conventional Zadra elution circuit. Suitable ancillary facilities are installed to supply flocculant, sulfuric acid, oxygen, lime, steam and compressed air to the autoclave facility.
