Since 2017, Barr has provided engineering services to a mine and processing facility that produces industrial chemicals. Projects have ranged from prefeasibility through execution for transportation and utility infrastructure, two process trains, and the tailings pond complex. Most recently, Barr completed detailed design for two new trash screens (which remove debris from the classifier overflow stream), including new piping, valving, nozzles, a trash-screen-support platform, a platform foundation, and electrical requirements.

At our client’s port facility, Barr conducted a feasibility study to relocate motor-control-center equipment to a safer and more centralized location and a prefeasibility study to replace an existing feed system before evaluating replacement options and developing cost estimates. Barr is currently assisting with execution of the project.

Barr also developed detailed engineering drawings and documents for a new truck-access road, including industry foundation classes (IFC) plans and specifications for the road, guard shack, security gate system, lighting, and electrical systems. Similarly, Barr conducted a prefeasibility study that includes a new rail spur and intermodal rail loadout.

We are also helping the facility address a byproduct build-up issue with a prefeasibility study that includes process modeling, preliminary design, and cost estimates; investigation of the structure and makeup of the tailings containment ponds; and dewatering recommendations to increase pond lifetime and facilitate pond closure.
