Gypsum industry news

UK: Formula, a brand of Saint-Gobain, has awarded a five-year contract to Darlington-based Banner Contracts to extract high purity gypsum from its opencast mine in Newark, Nottinghamshire. Banner Contracts was chosen after a tender process involving eight potential suppliers.

The opencast mine, known as Bantycock, produces around 230,000t/yr of gypsum. Nottinghamshire County Council agreed a revised restoration scheme at the site following consultation. So far this has seen the backfilling of 25 acres with overburden completed and covered with topsoil in 2016.

"Banner's professionalism and expertise is second to none so we are delighted to announce this contract. Its experience in mineral processing was a key factor in its selection as it will help us continue to improve our yield of useable gypsum versus the amount of rock we extract. This improved yield helps maximise the reserve life, whilst operating in a safe and sustainable manner. We look forward to a mutually beneficial relationship over the duration of the contract," said Saint-Gobain Formula Plant Manager Mark Yates.

Banner Contracts Director Jo Banner added that the contract is a large one for the company and that it has invested in a new plant and equipment. New installations at the site include a Hercules trommell commissioned especially for the application, a number of Tesab machines including a 800i jaw crusher, a TS1860 scalping screen, a TS2430 screen and a Trackstack radial conveyor and a sizer from MMD.

Australia: The framework is in place for a new wallboard plant that Knauf Plasterboard is building at the Port of Bundaberg in Queensland. A 27.8km gas pipeline that will support the project has also been laid, according to the Bundaberg Newspaper. The next step will be to commission the pipeline and commission off-takes. First gas flows are scheduled for mid-February 2017 whereupon it will supply the new Knauf plant that is expected to start production in June 2017.

France: Saint-Gobain has appointed Jean-Dominique Senard as Lead Independent Director. The newly created role will oversee the running of the company's governance bodies. Senard has been an independent director since 2012. The board of directors has also decided to appoint Senard as chairman of the Strategy and Corporate Social Responsibility Committee following the retirement of Jean-Martin Folz in June 2017. Philippe Varin will become the chairman of the Audit and Risk Committee and Anne-Marie Idrac will become the chairman of the Nomination and Remuneration Committee. All the personnel changes will take effect from 8 June 2017 at the company's annual general meeting.

China: 19 people have been prosecuted for misconduct related to the collapse of a gypsum mine in Shandong Province in December 2015 that killed one worker and left 13 persons unaccounted for. Yurong Company, owner of the mine, bears the principal responsibility for the incident, for failing to monitor and safely maintain the mine, according to the Xinhua news agency. Poor risk awareness and safety control, as well as inadequate regard for possible dangers in room-and-pillar mining were also causes the of the collapse. Yurong has been fined US$0.43m.

Three mine controllers, believed to be liable for the fatal accident, have been arrested by local police and two officials from the local land and resources bureau were found guilty of dereliction of duty. 14 other local officials have also been punished for violating the Communist Party rules. Ma Congbo, president of Yurong, who committed suicide after the accident, will not be subject to criminal liabilities.

India: Larsen & Toubro has signed a long-term technical licence agreement with Japan's Chiyoda Corporation for its Chiyoda Thoroughbred 121TM (CT-121TM) flue gas desulphurisation (FGD) technology. The agreement grants L&T exclusive rights to undertake engineering, procurement and construction with this system.

The deal follows a notification by the Ministry of Environment, Forest and Climate Change (MoEFCC) issued in December 2015 that placed new limits on SO2 emissions for coal-based thermal power plants. The legislation has called for mandatory installation of FGD systems in new power plants, including those currently under construction and many that are already operational.

In the CT-121TM FGD process developed by Chiyoda SO2 is absorbed from flue gas generated by coal-fired, oil-fired and other types of boilers and removed as gypsum. Unlike conventional processes in which the reagent slurry is sprayed on flue gas, the CT-121TM process uses Chiyodas unique absorber, the Jet Bubbling Reactor, in which the flue gas is blown into the reagent slurry, forming a fine bubble bed where SO2 is absorbed, oxidised by injected air, and then neutralised by ground limestone slurry.

Larsen & Toubro and Chiyoda's relationship dates back over two decades with L&T-Chiyoda Limited, a joint-venture catering to the hydrocarbon sector. Through the signing of this agreement, the two companies have extended their association into the power sector as well.
