The Kennecott Molybdenum Autoclave Process (MAP) project, the first of its kind in the world, is aimed at turning two obscure metals into valuable products. Kennecott estimates that the MAP project will produce 10 percent of the world’s molybdenum. Big-D Construction was selected to complete the structural concrete footings, foundations, piers, and slabs for the 
Because each autoclave project is site- and ore-specific, mining companies need an engineering partner with the right experience and expertise to provide the best solutions. Solutions Every autoclave and preleach circuit is a custom design, based on the experience and expertise of the design team.
Key lines of development of autoclave hydrometallurgy are described, especially low- and high-temperature processes, oxidation catalysts and chloride addition, processes inclusive fine and ultrafine grinding. It is given a brief overview of the autoclave enterprises practice relative to processing of sulphide copper-bearing raw materials.
Copper leaching from primary sulfides: Options for biological and chemical extraction of copper Clearly, the successful startup of the Alliance Copper project in Chile has validated the technology at a significant scale. The initial plant capacity is set for 60,000 tpa of copper. The autoclave oxidation of pyrite/sulfur will provide
Slurry from the grinding circuit, at approximately 35% solids and 80—85% passing 135 mm is pumped to three thickeners. Thickener underflow, at approximately 54% w/w solids, is pumped to a train of four acidulation tanks. Sulfuric acid is added to the slurry to destroy sufficient carbonate prior to entering the autoclave circuit. Process air is also injected into the acidulation tanks to aid

Our autoclave section is designed to give accurate mass and heat balances. It is also extremely versatile with respect to monitoring key parameters including temperature, retention time, sulfur fugacity and oxygen flow. Data collected during this testing is logged by process control systems, and can be reviewed and assessed by the project team.

Overview. High Pressure Acid Leach (HPAL) is a process used to extract nickel and cobalt from laterite ore bodies. The HPAL process utilizes elevated temperatures (roughly 255 degrees Celsius), elevated pressures (roughly 50 bar or 725 psi), and sulfuric acid to separate nickel and cobalt from the laterite ore.
