I been doing some inquiry for a modular gold mill. Maybe a good start. Once set up the gold is close to the surface and can begin produce result very quickly.
RMT does conduct recovery test work and we highly recommend carrying out a definitive metallurgical study on a representative sample of your material. A definitive study provides the metallurgical performance data needed to develop and design the processing flow sheet, equipment selection and sizing, accurately define the capital cost of the plant and determine the operating costs for the project. General information regarding project evaluations can be found at the following link:
RMT would require approximately 100kg of representative ore material to carry out a definitive metallurgical study. The studies take 6 to 10 weeks for completion and costs are approximately USD $ 150,000.00.
