+ When would a Dissolution Tubular Reactor be used?
Dissolution tubular reactors (DTR) are highly effective in leaching of refractory gold ores, flotation concentrates or gold ores that do not respond well to normal cyanidation conditions. In addition the DTR provides an economical and space efficient alternative to open tank leaching with superior performance.
+ How effective is a dissolution tubular reactor?
Dissolution tubular reactors are highly effective and can achieve considerably better gold recovery than open tank leaching in all applications.
+ Is it safe to use a dissolution tubular reactor?
Yes. DTR’s are carefully designed to produce highly effective leach conditions while remaining intrinsically safe.
+ Does the DTR work on gold ores containing sulfides?
Yes. Dissolution tubular reactors are particularly well suited to ores that contain sulfides and can make use of exothermic reactions with sulfides to produce superior leach performance.
+ How does a DTR compare to other gold leaching methods?
Dissolution tubular reactors are cost effective and compact with comparable operational expenses and improved leach efficiency.
+ How much does a DTR cost?
Dissolution tubular reactors are designed to match the application they are intended for and costs vary according to design parameters.
+ What information do you need from me to quote a dissolution tubular reactor?
Resources Gold Technology will need information on the composition and mineralogy of the gold ore to be treated as well as intended throughput. It is essential to have accurate information on leach kinetics in terms of standard and pressurized leach dissolution – time curves obtained from metallurgical test work.
+ Where can I get the information I need to get a quote?
You can contact us regarding recommendations for independent test work facilities with suitable equipment to perform the test work. Alternatively Resources Gold Technology can perform a metallurgical study for your application.
+ What is the function of the primary heat exchanger?
The primary heat exchanger transfers thermal energy from the outgoing slurry to the incoming slurry.
+ How does the primary heat exchanger work?
The primary heat exchanger is a conductive heat exchanger that functions by bringing outgoing slurry into close contact with incoming slurry.
+ Why is there a secondary heat exchanger?
The primary heat exchanger transfers most of the thermal energy for the tubular reactor to function. The secondary heat exchanger provides the additional thermal energy to bring the dissolution tubular reactor up to operating temperature.
+ How does the secondary heat exchanger work?
The secondary heat exchanger uses heated steam to transfer additional thermal energy into the tubular reactor system.
