Mine Design, Operations and Closure Conference Schedule
Monday, May 8, 2023
Field Trip: Graymont's Indian Creek Limestone Plant and Ash Grove Cement's Montana City Plant
Guides: Paul Liner and Doug Kuenzli
- 8:30 am to 4:00 pm (Bus will depart from the front parking lot at Fairmont Hot Springs. Please check in at the conference registration desk before boarding the bus. Hard hats, close-toed shoes, and safety vests will be required for all visitors at the mine site. Hard hats and vests will be available, if needed.)
- Breakfast and lunch will be provided.
The Graymont tour will consist of a site-specific training followed by a Graymont overview presentation. Attendees will be divided in half with one group taking a bus tour of the quarry and the other group touring the plant process and control room. Switch and repeat.
Ash Grove Cement
The Montana City Plant manufactures Portland Cement using a "wet" hydraulic cement process. The site located in Jefferson County, consists of approximately 2,200 acres that includes 841 acres within the mine operating permit boundary; 463 acres of which are permitted for disturbance. The main plan site which includes the production plant, raw material and fuel stockpiles, and shipping facilities consist of approximately 45 acres.
Operations occur in two distinct areas of the site. The Clark Gulch Quarry, the primary source of limestone, is located west of the community of Montana City. Raw materials extracted from the Clark Gulch Quarry using drilling and blasting techniques are campaign hauled to the plant site using over-the road haul trucks where material is introduced into the plant process or stockpiled for later use. A limited amount of raw material, mainly silica, is retrieved from the plant side quarry via scrapping and digging techniques.
The limestone, clay, and silica, along with fumed ASARCO slag, as a source of iron, is fed through the primary and/or secondary crusher and subsequently milled with water to form a slurry intermediate product. The slurry is pyro processed in the coal and petroleum coke-fired rotary kiln to form cement clinker and then finished milled with gypsum or limestone to produce Portland Cement.
The plant has a storage capacity of approximately 60,000 tons of finished cement product which feeds the truck and railcar loadouts areas. The Montana city plant produces 350,000 tons of cement annually which is distributed throughout Montana, Western North Dakota, Eastern Washington, and Canada. The Montana City plant has produced Portland Cement in the Montana City community for 60 years while employing 80 full-time employees.

3:30 pm Sustainable Mining Panel: Mining is critical to supply raw materials and resources to support important industries and all types of infrastructure, including green infrastructure. As demand for mined minerals continues to rise, debate on mining impacts to the environment and communities continues to grow. Now more than ever, miners need to focus on balancing mining operations with holistic environmental and social responsibility. Terms such as “Environmental, Social, and Governance (ESG)” and “Sustainability” are tossed around and politicized, but what do those terms mean and how can miners capitalize on these concepts to create social and financial value? This panel discusses topics such as ESG, sustainability, practical approaches and strategies, and appropriate metrics for reporting from the perspective of a mine, an attorney, a consultant, and an investor.
