Gypsum industry news

Ireland: France-based Saint-Gobain subsidiary Gyproc has applied to the Environmental Protection Agency (EPA) to have its sulphate discharge licence for its Drummond, County Monaghan, mine increased by 530% to 1250mg/l from 200mg/l. The Irish Independent newspaper has reported that the higher level ‘would not occur year-round,’ according to the company, but ‘only at certain times.’ The EPA is ‘awaiting additional information from the applicant in order to make a decision.’

US: The Bureau of Land Management (BLM) will be receiving public comment until 6 Feb 2020 on Eagle Materials' proposed 100 acre expansion of its 830 acre mine near Gypsum in Eagle County, Colorado. The mine supplies gypsum to its 67Mm2-capacity Eagle Materials gypsum wallboard plant in gypsum. BLM Colorado River Valley field manager Larry Sandoval said, “Responsible mineral development is part of BLM’s multiple-use mission,” according to RealVail newspaper.

UK: British Gypsum’s mine at Brightling near Robertsbridge has provided gypsum samples to researchers from the Natural History Museum. The rock specimens are intended to aid the scientists in looking at signs of past life in preparation for a joint European Space Agency and Russian Roscosmos State Corporation mission to send a robotic rover to mars in July 2020, according to the Rye & Battle Observer newspaper. Previously, NASA's Mars Rover Opportunity found bright veins of a mineral, which appeared to be gypsum, in 2011.

"Minerals like those found at Brightling hide clues within them that can tell us about the history of liquid water where they formed, and they have the potential to trap and preserve organic material. Studying these natural fresh samples on Earth that mimic not just the minerals, but also the formation environments we see on Mars, will give us an insight into the potential for life to be detectable at the ExoMars2020 landing site," said Louisa Preston, UK Space Agency Aurora Research Fellow and member of the Department of Earth Sciences at the Natural History Museum.

Canada: Red Moon Resources says it has shipped over 0.13Mt of gypsum and anhydrite from its Ace mine in western Newfoundland since May 2019. Production is scheduled to continue into late October 2019 and the company is expecting for total production to exceed 0.15Mt in 2019. The company is working with Vinland Materials, a related company, to undertake contract mining operations and secure sales agreements for gypsum and anhydrite.

“We have successfully opened up the Ace mine and will continue to work towards a larger operation,” said Patrick J Laracy, President of Red Moon.
. “We have engaged some of the best operational resources in the area to make the mine a success and ensure its viability. The economic impact in the immediate area is significant with an estimated 45 people employed on a seasonal basis in mining, trucking, port facility, marketing, shipping and supervision. This is in addition to the utilisation of specific services such as drilling and blasting.”

Red Moon uses a deep-water port approximately 10km from the mine to ship the gypsum. The quarry site covers 12 hectares and has the potential for a 10 year mining life at an average production rate of 350,000t/yr. The company says that if it can access markets requiring production rates beyond the Ace mine capacity, the company is prepared to develop other existing gypsum deposits located on its mineral licences, which cover approximately 700 hectares of the historic Flat Bay gypsum mines.

US: Gypsum Resources has filed for Chapter 11 bankruptcy at the Nevada US Bankruptcy Court. It is aiming to reorganise the business amid financial and operational difficulties, according to the Las Vegas Reiew Journal newspaper. The company operates a gypum mine at Blue Diamond Hill but it has been trying to develop a residential housing project at the site for over a decade. The development has been opposed by local environmentalists.

Company president James Rhodes blamed the bankrupty decision on ambitious growth plans, disrupted mining operations due to equipment failure and bad weather. He was optimistic that market demand for gypsum is steady and that the company will report positive net income later in 2019. The mine supplies gypsum to the wallboard, cement and agricultural industries.

Canada: Red Moon Resources has loaded its first shipment from its Ace gypsum mine in western Newfoundland. The company is working with Vinland Materials, a related company, to undertake contract mining operations and secure sales agreements for gypsum and anhydrite. A deep-water port connected by a haulage road is located approximately 9km from the mine. The site covers approximately 11.79 hectares and has the potential for a 10 year mining life at an average production rate of 350,000t/yr.

Canada: Red Moon Resources has submitted a development plan for an open cast gypsum mine at the Ace deposit in western Newfoundland to the government of Newfoundland and Labrador. The project has already received environmental clearance. It is currently attempting to find customers for gypsum and anhydrite from mine. Previously the site was used by the Flat Bay mine, which produced at least 15Mt of gypsum prior to 1990.

Red Moon Resources is an industrial minerals company developing the Ace Gypsum deposit, the Black Bay Nepheline deposit and the Captain Cook Salt deposit in Newfoundland and Labrador. Its majority shareholder is Vulcan Minerals.

Iran: Azerbaijan’s Matanat-A gypsum plant is estimated to cost around US$10m. The head of mining and industrial organization of Semnan Province, Behrouz Asfadi, said that production at the plant was expected to start in the ‘near future,’ according to the Trend News Agency. Jafar Sarghini, the deputy minister of industries, mining and trade, added that Matanat-A is already using a gypsum mine in northern Iran and the plant is expected to be located nearby.

Canada: The British Columbia government has granted an environmental assessment certificate for a 0.4Mt/yr opencast gypsum mine in West Kootenay proposed by CertainTeed Gypsum Canada. Construction of the project is expected to cost US$19m, according to the Canadian Press. Gypsum from the mine will be used to manufacture gypsum wallboard, cement and plaster products.

Australia: Clean TeQ plans to build a 2Ml/day DeSALx mine water treatment plant for Fosterville Gold Mine for its mine near Bendigo in Victoria. The US$2.7m unit will use an integrated precipitation and continuous ionic filtration process (DeSALx) that will produce a gypsum-based by-product. This by-product will be compatible with Fosterville’s existing lime treatment plant. Equipment supply, installation and commissioning of the water treatment plant are scheduled for 2018.

The precipitation process removes arsenic and antimony from the mine water as a co-precipitate. The water is then treated by the DeSALx process to remove hardness, sulphate and other dissolved metals. Clean TeQ is also in talks with other mining companies to test its continuous ion-exchange systems for the treatment of process water treatment for recycling or environmental discharge.
