The BIOX #174; plant consists of two modules of seven BIOX #174; reactors, followed by CCD washing, solution neutralisation and CarboninLeach for gold recovery. After approval of Bogoso Sulphide Expansion Project, construction commenced on 13 June 2005. GRD Minproc was awarded the contract for the design and construction of the project.
Over 25 million ounces of gold produced with the BIOX process. from ~19kg/t for the standard BIOX mesophile to 8 kg/t for the MesoTHERM product while maintaining the same gold recovery
The Runruno Gold Project is located on the island of Luzon, approximately 200 miles north of Manilla in the Philippines. The mine is an open cut operation and uses the proven BIOX#174; and carboninleach (CIL) processes to recover gold, and the ASTER process for detoxification of the CIL residue prior to discharge to the Residue...

Abstract. GENCOR Ltd. has pioneered the commercialization of biooxidation of refractory gold ores. Development of the BIOX #174; process started in the late 197os at GENCOR Process Research, in Johannesburg, South Africa. The early work was championed by Eric LiveseyGoldblatt, the manager of GENCOR Process Research who directed pioneering and innovative research into bacterial oxidation
#0183;#32;The BIOX#174; reactors were fed with a bulk flotation concentrate (pyrite and arsenopyrite) with an average gold grade of oz/ton ( g/ton). The gold recovery from the biooxidation product was in excess of 85% with a retention time of between 4 and 6 days in the BIOX#174; reactors.
Gold Recovery: Wait dont throw those old electronics in the garbage, theres gold in them there things. How about putting it in your pockets instead of someone elses pocket? Laptops, phones, cameras, and the like are filled with gold plated circuit boards even

Gold Recovery Correctly: I will detail a SAFE process of turning old electronic parts into little round lumps of pure gold. There are many tutorials that claim to offer methods of gold recovery such as quot;Cupellationquot;*. These processes are DANGEROUS and put the user at the
Outotec BIOX#174; Process. Optimize overall gold recovery and reduce capital costs with the Outotec BIOX#174; process. The process was developed for the pretreatment of refractory concentrates ead of conventional cyanide leaching for gold recovery. As the gold is encapsulated in sulfide minerals such as pyrite and arsenopyrite, the gold is
#0183;#32;Biohydrometallurgical process routes for gold recovery from sulphidic concentrates have typically not recycled cyanidation wastewater due to historical process
The BIOX bacterial oxidation process is currently used commercially to treat refractory gold deposits at ten gold mines on four continents, including the Fosterville mine of Kirkland Gold located in Victoria province of Australia. It has facilitated the production of more than 24 million ounces of gold
recovery of the balance into the BIOX#174; solution. However, to date testwork at the pilot plant has been prioritised for the achievement of gold recoveries (%), and it is only now, with the gold testwork substantially complete, that resources can be directed towards demonstrating molybdenum recovery from solution into a saleable product.

TECHNOLOGY. The typical process flow sheet for the BIOX #174; process is shown below.. Feed Preparation. The sulphide concentrate from the flotation section of the plant is pumped to the BIOX #174; stock tank. Flotation concentrate is thickened to a density of at least 50% solids to minimise carryover of flotation reagents to the BIOX #174; reactors. A minimum sulphide sulphur concentration of
biox gold processing. The BIOX process destroys the sulphide minerals and exposes the gold for subsequent cyanidation thereby increasing the overall gold recovery that can be achieved BIOX advantages The plant design offers a low capital cost solution reliable process performance and the application of robust energyefficient equipment The BIOX process can operate
The BIOX#174; process is a patented technology for pretreatment of sulphidebased refractory ores and concentrates ead of a conventional cyanide leach for gold recovery. Outotec, the owner of the patent has produced an ASTER process design package for
