Hazen Research, Inc. is an employee-owned industrial research and development firm located in Golden, Colorado. The company was founded in 1961 by a small group of metallurgists with strong backgrounds in research and process development for the mining and chemical industries. Over the years, Hazen has grown to its present size of 190 employees with 18 buildings containing an extensive inventory of laboratory and pilot plant equipment. We serve clients from all over the world on projects ranging from bench-scale experiments and analyses to multimillion-dollar continuous pilot plants.

We have completed over 12,000 projects for industrial clients, and our range of services now extends to the environmental and energy industries. In addition to our research and development activity, we can provide the preliminary layout and cost estimation for small-scale industrial chemical plants and mineral-treatment facilities. The growth of our ability to fabricate and operate small demonstration plants has required a parallel development of sophisticated data acquisition and computer modeling methods.

Hazen has developed hundreds of hydrometallurgical, pyrometallurgical, and mineral beneficiation processes for most commercial metals and industrial minerals, and for many inorganic chemicals. Our energy clients have utilized Hazen’s expertise to develop processes involving coal upgrading, combustion of alternative fuels, and conversion of a wide variety of feedstocks into energy sources. Waste characterization and treatability studies, waste reduction options, and valuable byproduct recovery from waste streams are routinely performed for industrial clients.

Our strength is the ability to understand and provide service in the entire spectrum of activity from the starting material – whether an ore, coal, or waste stream – to the finished product.
