Multi-Member Process & Application Consulting Group
Comminution Circuits, Material Handling, Heap Leach Circuits, Hydrocyclones, Screens, Air Classification Circuits, Pyro Processing Systems, Flotation Circuits, Filtering / Clarification, Dewatering and Specialized Professional Training

To showcase, we have recently been deeply involved in the selection of equipment for three Dry Grinding Plants. The material to be processed is silica, clay, and pozzolan.
 
We specialize in most forms of Comminution. Having said that, our main focus currently has been Dry Grinding Systems for industrial minerals (silica, clay, pozzolan, calcium carbonate etc.) and complete plant sizing and application of the process to select the circuit equipment.  Give us a Call!  
Professional Excellence ​
EdRockMan IV LLC is a collection of accomplished experts proficient in their consultant trade with exceptional skills and knowledge gained by being involved in the majority of the largest comminution projects in the world over the last 30-40 years.
We bring a group of experts that are experienced in multiple disciplines concerning the process application, scale-up, start-up, and operation of comminution circuits - specializing in   
material handling, HPGR's, mills,crushers, and pyro 
processing circuits/application. This includes drying and roasting, pressure hydrometallurgy, Pressure Oxidation (POX) for refractory gold and HPAL for nickel cobalt laterites.   

Training
We can provide comprehensive sales training - single or multiple day technical seminars that can be led by a professional speaker who specializes in human potential motivation. We have access to various training experts and academic material that can be customized to best suit your training goals.Technical training can be done on comminution, pyro-processing, mineral processing, and chemistry for chemical companies and metallurgists. Further information can be found on our products page.

Flow Sheet development
EdRockMan has specialists in flowsheet development for mineral applications, mineral processing plants and industrial mineral applications. We have been involved in successful heap leach operations, implementation of gold and silver agitation, leach/CIP operations and plant ramp-up. In addition, EdRockMan members have designed and built various concentrators and processes currently in operation (diamonds, platinum-nickel-gold, copper, nickel plants). Some of our members have engineered, installed, and operated various column flotation operations. Other members lead development of novel methods in the processing of diamonds, copper, nickel, potash, silver, lead, titanium, oil sands, bioleaching, and technical experience. Moreover, EdRockMan can provide process development testing of base metals, precious metals, coal, uranium, iron ore, and rare earth mineral projects.
