Material Handling in Mining Operations | EARTHRES Engineering

Project Background

When our client, a leading mining company, struggled with underutilization of their sand plant, they sought out EARTHRES for a solution. The plant, operating at only 36% capacity, relied on haul trucks and loaders, causing inefficiencies. EARTHRES conducted a thorough assessment and designed a reclaim and conveyor system to streamline the feeding process, boosting operational efficiency and eliminating the need for heavy equipment. The result was a dramatic increase in production, reduced fuel consumption, and faster return on investment, delivering significant long-term benefits for the client.

The Results

Implementation of the new Reclaim and Conveyor Circuit as designed along with comprehensive support from EARTHRES brought significant benefits to the client: 

• Increased Production Rate: The production rate increased from an actual 250 TPH to a design potential of 800 TPH. Actual operations have been running at 650 TPH on average.
• Return on Investment: In the design phase, an ROI Analysis showed full payback in 6 months; however, once installed and operating, the actual payback time was only 4 months!
• Reduced Fuel Usage: In eliminating the vehicular use to feed the sand plant, the vehicle miles traveled, emissions, over 100,000 gal/yr of fuel were no longer needed to transfer sand from the surge pile to the feeder.
• Reduced Power Usage:  The total power usage for the Sand Plant Operation was reduced by 1,046 HP.
• Reduced Carbon Footprint: Greenhouse gas (GHG) emissions were reduced by over 1,055 TPY.
