:: CEEC Celebrates Value-Adding Mine-To-Mill Options With New Sponsor Hatch


A new sponsorship agreement with the award-winning team at Hatch will help CEEC share mine-tomill, energy-efficiency and productivity improvements across its global network. An industry leader and CEEC champion, Hatch specialists bring leading insights across the mining value chain. They have contributed practical mining and processing improvements over 420 global optimisation projects.

The Coalition for Energy Efficient Comminution (CEEC) is an international not-for-profit organisation which aims to increase efficiency of minerals production by communicating and celebrating best practices throughout the industry. It is entirely funded by sponsorship from the minerals industry. CEEC helps to lower costs, improve shareholder value and support sustainable minerals production. CEEC CEO Ms Alison Keogh said she was pleased to announce the Hatch sponsorship agreement. “There’s great synergy between what Hatch and CEEC are striving to achieve through the sharing of smart practices. We’re proud to be working together in this endeavour,” she said.

Ms Keogh said Hatch was no stranger to CEEC, and Hatch is recognised through its people, with highly respected experts in mining, comminution and processing. “Hatch Global Director Mining and Mineral Processing, Mr Ivan Mullany, volunteers his time as a CEEC director, and has done so since 2013,” she said.

Alison added “Hatch Global Director Consulting and Technology, Dr Walter Valery, was awarded the prestigious CEEC Medal in 2012 for his contribution to an inspiring case study at Antamina in Peru. The team demonstrated important ways for miners to enhance value and also reduce energy through smarter comminution practices.”

Dr Valery said the approach in the Antamina project helped identify value and other benefits by treating harder and softer ores differently. “Energy savings of 25% were achieved. Throughput when treating harder ores increased from 2600 tph to 4500 tph while specific energy consumption reduced from 14 kWh/t to 10 kWh/t,” he said. He highlighted the value to miners “This increased resource efficiency and reduced total environmental impact of metal concentrate production. This was done by integrating and optimising drill and blast with the comminution circuit. It led to more sustainable throughput and profitability.”

Ms Keogh said the abstract of the winning paper "Optimisation and continuous improvement of the Antamina Comminution Circuit" is available on CEEC’s website, along with other medal winning contributions and inspiring case studies of success. She said “The CEEC Medal is an international award that recognises and celebrates the contribution of outstanding published papers, articles and case studies that capture strategies for energy efficient comminution, which is the process in which solid materials are reduced in size by crushing, grinding and other processes.”

Former CEEC Medal winner Dr Valery said Hatch was delighted to build on its existing relationship with CEEC through this sponsorship agreement. “The mining and metals industry is facing declining feed grades and increasingly tough economic conditions. Miners need to operate more efficiently to meet environmental targets, but also to remain economically viable. This is a key focus for CEEC and Hatch,” he said.

“At Hatch we work with our customers to develop new ideas, technologies and innovations to improve resource efficiency. We maximise the recovery of value from an ore deposit while reducing environmental impact. In existing operations, we often do this with little or no capital expenditure. It’s all about understanding the ores, each stage of the operation, and how they all interact,” he said.

Walter shared “In greenfield projects, we integrate mine and plant design, considering a range of possibilities and opportunities. This may include high intensity blasting; early waste-rejection; alternative energy efficient comminution technologies; coarser primary separation; and less fine grinding. Taken in part, there’s improvement. Taken together, there can be transformation.”

Hatch’s experts work as a team to tackle and deliver the right integrated solutions across every step of the mining value chain. In collaboration with its clients, Hatch specialists have published more than 190 technical papers. Many showcase results of consulting and technology projects which have helped the mining industry improve productivity and energy efficiency.

Ms Keogh said Hatch was a welcome addition to the sponsor team. Without sponsor support, CEEC would be unable to deliver global workshops on energy-efficiency and free tools that mining and METS companies are using to inspire, benchmark and track their improvements.

“We appreciate and acknowledge the valuable support of Hatch and our other visionary sponsors, who are actively engaged in adding value to miners and leading positive changes globally” she said.
