MineSense to expand XRF ore sorting presence at Copper Mountain mine

MineSense Technologies says the use of its ore characterisation and sorting technology is seeing improvements in both the ore from waste recovery and ore dilution at Copper Mountain Mining Corp’s namesake mine in British Columbia, Canada.

Having deployed the company’s ShovelSense solution on two shovels and a wheel loader in 2020, Copper Mountain now has plans to install ShovelSense on the two remaining shovels in 2021, along with the first trial installation of BeltSense to explore additional innovation concepts, Don Strickland, Chief Operating Officer at Copper Mountain Mining Corp, said.

Jeff More, President and CEO of MineSense Technologies, said: “Copper Mountain has been a fantastic partner to work with, initially to support us in our scale-up on hydraulic shovels, and then with rapid commercial deployment once the design was stabilised.

“We are thrilled that they installed three of our ShovelSense Systems in the space of five months in 2020 and will complete installation of their entire shovel fleet in 2021.”

The MineSense hardware and software went through a two-year evaluation process at Copper Mountain prior to the solution going commercial, Copper Mountain stated in a recent technical report.

The ShovelSense system improves orebody visibility bucket by bucket in real time during the loading process, according to the company. Trucks are then automatically diverted to the correct location, increasing value and revenue realised during the mining process. The technology also creates reductions of CO2 emissions per tonne of ore produced, consumption of processing chemicals and reagents, energy and water, while maximising metal recovery.

BeltSense, meanwhile, is used on conveyance at different points of the mine operation. It can be used sequentially and in conjunction with ShovelSense to maximise the ore concentrating impact, taking a first cut at the haul point and second further downstream, MineSense says.

Both systems leverage X-ray Fluorescence sensors to carry out the sorting process.

Cat revamps 6060 hydraulic mining shovel

Caterpillar has launched its next generation 6060 hydraulic mining shovel, which, it says, features multiple design enhancements and new components that advance machine performance, durability, serviceability, and operator comfort.

The new 6060, which replaces the 6060B in the hydraulic mining shovel lineup, features updated engines, optimised hydraulics, heavy-duty structures and undercarriage, Cat electronics and a state-of-the-art cab, according to the company. It is also fully integrated into Caterpillar product support systems for efficient Cat dealer services.

One of these new-generation shovels is set to operate at Anglo American’s in-development Quellaveco mine, in Peru, as part of a fleet that includes autonomous 794 AC trucks.

The 600-t class mining shovel has a bucket payload of about 61 t/pass in both face shovel and backhoe configurations. This makes it an efficient four-pass match with the 231-t payload Cat 793 mining truck and five-pass match with the 291-t payload Cat 794 AC mining truck.

Twin Cat 3512E engines are optimised for high performance, fuel efficient operation and increased durability, according to the company.

For North America, the engines are equipped with a maintenance-free diesel oxidation catalyst emissions control system, do not use diesel exhaust fluid and comply with US EPA Tier 4 Final regulations, Cat says. The updated engine design boosts reliability and extends time between overhauls by 10%.

The combination of this updated engine and optimised hydraulics enables 10-15% percent better fuel efficiency compared with the previous face shovel model, with 3-5% greater efficiency for the backhoe configuration, Cat says. For reduced maintenance, engine oil and filter change intervals are doubled to 1,000 hours.

Structural, undercarriage and slew ring upgrades help maximise uptime and productivity and lower cost per tonne, according to Cat. To boost longevity, the Cat undercarriage features heavy-duty rollers, idlers and tracks, along with a revised track tensioning system. The superstructure frame, face shovel and backhoe attachment structures, meanwhile, have been redesigned to reduce structural repair and extend service life via increased plate thicknesses and geometrical improvements. The slew ring design extends component life with a triple-race roller bearing and sealed internal gearing.

“The 6060 features a new, state-of-the-art cab and operator station with industry-leading visibility provided by the large floor window and expansive windshield and side windows,” Cat said. “Unrestricted lines of sight to the crawler tracks and pit floor aid the operator when repositioning the shovel and when loading trucks.”

A pneumatically cushioned operator seat can be heated and ventilated. It also has integrated joysticks and is multi-adjustable to offer optimal ergonomics.

This cab also includes two additional seats: a full-size seat and laptop desk for a trainer and a fold-up seat for an observer. The three-seat cab design is the first in this size class of shovels, Cat says.

Improved sound suppression on the power module keeps spectator sound levels low, while the sound suppressed cab provides a quiet working environment for the operator, according to the company.

The first of several features within the available Operator Assist suite, Enhanced Motion Control is standard on the shovel. This improves machine controllability and loading efficiency while reducing linkage and cylinder mechanical contact, according to Cat.

The machine’s five-circuit hydraulics design allows simultaneous control over two cylinder motions, two travel motions and swing to boost digging and loading efficiency, the company added.

The next-generation design helps improve service and maintenance efficiency by offering more room inside the service compartment and easy ground-level accessibility to the service station, Cat says.

Integration of Cat hoses in the design allows for local hose sourcing, while improved hose and component organisation further reduces machine downtime.

Sensors located throughout the 6060 monitor operating data, record faults and give audible and visual notifications of issues to the operator. Product Link™ Elite, which is standard for the first time on the 6060, enables data communication for remote machine health monitoring.

The 6060 comes ready to accept Cat MineStar™ Solutions, a suite of mining technologies geared to enhance mine safety, improve efficiency and reduce operating costs.

In addition to the next generation diesel-powered 6060, Caterpillar continues to offer the electrically powered 6060 AC FS (face shovel) for mines optimised for such machines.

LiuGong appoints Kris Kulkarni as it strives for ‘world-class’ mining product line

LiuGong Machinery has made Kris Kulkarni Vice President, Global Mining, at LiuGong North America.

Kulkarni began his professional career at Caterpillar, in 1996, in structures, and steadily progressed in engineering roles across diverse mining products including large wheel loaders, mining trucks, surface drills, and hydraulic shovels, LiuGong said.

“LiuGong has an emerging portfolio of mining products, including trucks, large tonnage wheel loaders, excavators and bulldozers,” the company said. “Kris is exceptionally well qualified to help lead the transformation of this mining product line to world-class levels.”

LiuGong Vice President of Strategy & Aftersales and Chairman of LiuGong North America, Kevin Thieneman, said: “Kris’ extensive background and knowledge of the mining industry brings an exciting new dynamic to our company. As LiuGong is committed to expanding not only product its current line-up of mining machines but its overall understanding of these highly specialised customers, Kris will be an invaluable part of that growth.”

Kulkarni said: “I am excited to have the opportunity to join an organisation so focused on customers and employees. LiuGong has a rich 60-year history, and an inspiring vision for its future. I look forward to helping write the next chapter as we broaden the portfolio by designing and manufacturing machines in a larger-size class which offer our customers the lowest total cost of ownership.”
