Projects include: waste rock facilities, tailings dams, tailings dry stacks, codisposal facilities, and heap leach pads. Our team members have completed numerous heap leach pad and waste rock dump designs throughout the world including locations such as Alaska, Nevada, Mexico, Arizona, Turkey, Armenia, and Peru.
mine waste is produced and disposed in higher quantities due to the increasing mineral demand and the diminishing high grade ore reserves. In Peru, mining operations deal with the rugged, mountainous and many times aggressive Andes terrain. For this reason, when designing a mine waste dump, problems such as slope sta

Design and Evaluation of Tailings Dams 1 DESIGN AND EVALUATION OF TAILINGS DAMS 1. INTRODUCTION In order to obtain the metals and other minerals needed for industrial processes, fertilizers, homes, cars, and other consumer products, large quantities of rock are mined, crushed, pulverized, and processed to recover metal and other mineral values.
open pits, may be used to construct new, or extend the life of, tailings dams. Permanent heap leach pads and heap leach spoils: A constructed stockpile of agglomerated ore is prepared for the purpose of leaching by means of percolating a solvent though the ore. The stockpile is placed on a lined solution collection and containment pad.
Projects included leach pads, tailings storage facilities, containment structures, waste rock facilities, ponds, road crossings and storm water diversions. Mr. Cooper has had an abundance of experience in leach pad and tailings storage facility design and construction.
