Underground Coal Gasification

The pilot scale UCG process produces only a small stream of syngas that is flared, but plans call for a 1,200-MW UCG plant and an IGCC plant constructed in parallel. In the United Kingdom, the government undertook a five-year effort to review UCG and study the feasibility of using the technology for exploiting coal on land and offshore.

Cypress Development Studies Chloride Leaching for Clayton

Cypress continues to work on the pilot plant as recommended in the Company's positive May 19, 2020 Prefeasibility Study (PFS). The project is based on a surface mine producing 15,000 tonnes per day (tpd) of lithium-bearing claystone to a leach plant yielding 27,400 tonnes per year of lithium carbonate equivalent (LCE) over a 40-year mine life.

Leachate treatment | Waste Management World

A fullscale plant was constructed and commissioned as a preaerobic biological treatment process step. At SENT, a strict limit of 200 mg/l "total nitrogen¿ for the treated leachate was applied and pH-driven air stripping of ammonia was installed and commissioned from the beginning. Aerobic biological treatment at Buckden Landfill

Bioleaching: metal solubilization by microorganisms | FEMS

In the 1970s the largest plant for microbial leaching was that for dump leaching of the Kennecott Copper Corporation at Bingham, UT, USA. The contents of the dumps stored there were estimated at more than 3.6×10 9 tons and about 200 tons of copper were recovered every day by bioleaching.

Enumeration and Characterization of Acidophilic Microorganisms

2003/4/1 · The pilot plant was part of a bioleaching optimization program that had been running for more than 1 year, initially in the batch mode and later in the continuous mode. The system had been inoculated with an undefined culture of moderately thermophilic acidophiles that had previously been maintained on a similar concentrate.

Continuous biological tank leaching of a refractory arsenical sulphide concentrate to enhance gold extraction by cyanidation : a pilot plant

The laboratory data provided the design and operating criteria for a continuous bioleach pilot plant. Operation of the continuous pilot circuit, with a nominal design capacity of 2 tonnes per day, showed there was no significant effect of scale on the biohydrometallurgy

Complex processing technology of gold-bearing concentrates

The object of investigation is an autoclave cake of the refractory gold-containing flotation concentrate prepared using a pilot plant. The influence of heat treatment (HT) on the chemical composition and recovery of gold is investigated for this material in a temperature range of 100–500°C. Due to the HT, it is possible to acquire high recovery of gold up to 98%. This is attained due to

Kalna Uranium Milling Pilot Plant | Facilities | NTI

The semi-industrial plant at Kalna was constructed to separate ore extracted from Mt. Stara Planina. In 1960, it was operating with a capacity to process between 23 to 50 tons of ore per day. During the 1960s, the plant conducted "large-scale" uranium ore processing experiments to become familiar with the technologies and processes, and to obtain necessary information to design industrial

Copper leaching from primary sulfides: Options for

Over the last 10-15 years, a variety of biological and chemical leaching processes have emerged for overcoming the passivation of chalcopyrite. A number of these processes are now entering commercial production or are approaching this status. The BIOCOP™ process of BHP Billiton has now been commercialized at the Alliance Copper plant in Chile.

Leaching Plant Design - Mineral Processing & Metallurgy

Leaching plants, faced with increased tonnage, coarse (up to —3/16″ solids) feed, longer retention time, erosion, corrosion and the high cost of space, must be compact, simple and highly efficient. The engineer faced with the obvious economy of using a few large agitators compared to many smaller units must also evaluate the design factors which will prevent the settling-out of solids
