QUALIFICATIONS: * Professional Engineer in the US, and Certified Manager in Australia, with over 25 yrs of mines design, process plants, and mining infrastructure. - My responsibility includes: detailed design, mining operation safety (specific for each geological formations), and all the environmental conditions, related to the project e.g capture the cyanide chemical from gold tailings. - Proven project management skills, with a track record of completing projects under stringent timelines and budgetary constraints, including supervision of 200-250 engineers, 30 contractors, and 3000-4500 labor force at the site. - Responsible for large-scale feasibility study, exploration budgets, cost of development and operating of surface and underground mines and process plants, financing the mining study ventures, and project risk analysis. on tunneling and shafts development. - Experience on flotation smelter and metal refinery design and construction supervision. Private Consulting Mining Engineer- from June 2013 and in present. I am doing economical study for different banks in South America (Chile Peru) such as mines profitability feasibility studies for surface or underground ore bodies Contracts Manager- from April 2012 to June 2013. Government for overburden storage, and flotation location. owner). The ore body approx.. 200M tons of bauxite study was financed by the UN because the country is very poor. The nearest distance to the ocean was 500 km. A feasibility study for 25,000 tpd with benches of 25 ht high 189 t trucks and 30 cu yd shovel were recommended. To create jobs on that area has been decided that the Alumina plant to be constructed near the mine. The final product Alumina will be transported by rail to the ocean 500 km loaded on ships and transformed on Aluminum metal in South Africa. "Questa" an u/g Molybdenum Mine located in New Mexico. Initially this ore was mined on surface mine. Ralph M. Parsons was in charge to develop a feasibility study for developing a u/g mine at 25,000 tpd using block caving method. For hoisting ore 2 friction hoist shafts at 25 ft dia x 2000 ft depth and a decline from the surface for men and materials. A new flotation an rail spur tailings dam and an safety pillar between the surface mine bottom and the new u/g mine also were included. The cost of this project was approx.. $300M. "Oil Shale"- u/g mine located on C-a and C-b tracts in Colorado. Was a joint venture between Occidental Exxon and Ashland to develop an u/g mine at 3000ft depth open large blocks at 400 x 400 x 600 ft high by hoisting at the surface only 25% of rock and the difference of ore was blasted in situ (Rubblezation in situ method). After the blocks were blasted a power flame is initiated at the top of each block. With the help of u/g air ventilation travelling from the top of block through broken rock the Melted oil from the rock is collected at the bottom of each block and pumped out at the surface. To cool the flame at the melting rock oil face the flame was cooled with steam which was produced at the surface. from Salt Lake city (u/g coal mines modernization). I supervise a project (detail design) for 5 u/g mines to change the existing method of room and pillars with longwall 1000 ft faces using equipment from "Dowty" UK and "Feromatik". Germany. The coal thickness was 7 ft at 8000-12,000 Btu. The project also included a detail design for a new 2000 MW electrical power using coal from these mines. Ralph M. Parsons was not involved on construction supervision.
