About Copper Mountain Mining Corporation Copper Mountain’s flagship asset is the 75% owned Copper Mountain Mine (CMM) located in the Canadian province of British Columbia near Princeton. CMM currently produces approximately 90 million pounds of copper equivalent per year. Copper Mountain Mine is a conventional open-pit, truck, and shovel operation. The operation has a 40,000 […]

Copper Installation- Deep Dive into Efficiency                                                                                                                  The Scenario: Using the current footprint, the customer wanted to replace an existing screen in a Sag Mill copper installation with a General Kinematics STM-SCREEN™. The SAG discharge screen experienced surges of material (25%-40% solids) from the SAG mill, which overloaded their existing screen. During these frequent overload […]

The General Kinematics STM-SCREEN™ Two-Mass Vibratory Screen is changing screening at Copper Mountain Mine. Watch this video to hear how the new screen is improving performance and lowering maintenance costs:  Want to learn more about the STM-SCREEN™? Check out photos, videos, and case studies here!

In 2016, a CPP coal mine site in Australia wanted to handle higher ash seams than the CPP had been designed for. It also was looking to recycle coking coal tailings to produce a thermal product. To achieve this, the mine needed an increased reject screen capacity of up to 1000 tph from their current […]

Artisanal miners can be found around the world outnumbering the industrial mining population 14 to 1. From panning for gold in a stream to operating their own claim with their own elaborate processing system. Whether it is done as a hobby or a full-time job one thing is for certain: artisanal mining is a way […]

A Canadian mine was dealing with the effects of an unreliable screen positioned at the discharge end of a Sag Mill. In addition to creating downtime, the brute-force screen was not processing the desired load of wet copper ore. Understanding the process and the level of reliability that the process needed, General Kinematics’ talented subject […]

Challenge General Kinematics was given a challenge. A screen for sizing limestone was sitting over 100 feet in the air atop a silo. Due to the difficult access point, it needed to be replaced with a reliable screen that did not get jammed or need maintenance often. The inquiring company sent their material to GK […]

Challenge A major mine in South Central China was in the market for two new screens for iron ore processing. The vibrating screens they owned had been installed two years previously by another manufacturer. Since installation, the screens had experienced severe resonance issues and were literally shaking apart. As the amplitude would increase to process […]

Challenge A Canadian gold mine was looking to partner with a vendor that could meet their standards for optimizing their process and a machine capable of handling their increased production volume, with lower overall operating cost. They needed a unit that could accomplish the grueling task of sorting their extracted materials to a size of […]

Challenge In a process used to make quicklime, a substance used in cleaning solutions, paper mills, and the food industry among other applications, limestone is mined from calcium carbonate deposits. Once the soon-to-be quicklime limestone has been extracted from the ground it is sorted by a preliminary screen to be a maximum size of 6”. […]
