In 2009 it was one of the 100 largest companies in Canada, with sales over CDN $1 billion.The company was founded in Toronto, Canada, by W.S. Atkins as W.S. Atkins & Associates in 1955. The company initially was involved in subway tunneling and other civil engineering projects, and expanded into metallurgy when Gerry Hatch joined the company in January 1958. It became known as Hatch in 1962. Hatch counts among its metals clients the top 20 mining and metals companies in the world, including Alcan, Alcoa, BHP Billiton, Barrick Gold, BlueScope Steel, Xstrata , Vale and Rio Tinto.In 1996 the company began an expansion program by purchasing several aligned engineering companies including Billiton Engineering , Rescan Mining , BHP Engineering , Kaiser Engineers , Acres International , and MEK Engenharia . By 2005 the combined billing of the company was around CDN $700 million.Hatch today provides consulting, operations support, technologies, process design, and project and construction management to clients in three principal sectors: mining and metals; energy; and infrastructure.The company's main offices are in Canada, Australia, South Africa, Chile, China, Brazil, Peru, Russia, United Kingdom, and United States.

Hatch Ltd. | Date: 2015-04-27

A highly flexible sealing arrangement designed to seal high-temperature furnace ports, particularly the electrode port of an electric furnace. The seal comprises an annular support member fixed to a flexible sealing member and employs the use of a garter spring to uniformly apply the desired amount of seal compression. The arrangement and flexibility of the sealing member allows the seal to adapt itself to the wide range of operating and upset conditions that typically exist for a furnace electrode seal. Frictional wear on the seal may be greatly reduced as the design inherently allows for a much lower amount of seal compression to be applied, furthermore, the seal is able to move axially which can significantly reduce wear caused by electrode regulation.


A process for preparing solid slag granules from a molten slag composition comprises: (a) providing the molten slag composition; (b) converting the molten slag composition into the solid slag granules in a dispersion apparatus; and (c) sorting the solid slag granules by shape in a separator to produce a plurality of fractions having different sphericities. Granular slag products comprise one or more fractions of solid slag granules produced by the process, and include proppants, roofing granules, catalyst supports, which may be porous or non-porous, and coated or uncoated.


A reactor comprises an outer sidewall and a bottom wall enclosing a hollow chamber comprising a lower fluidized bed zone and an upper freeboard zone. A plurality of inlets is provided for injecting at least one fluidizing medium into the fluidized bed zone and creating a swirling flow. At least one feed inlet communicates with the fluidized bed zone; and at least one product outlet is provided for removing a product from the chamber, the outlet(s) communicating with either the fluidized bed zone or the freeboard zone. The reactor has at least one internal barrier located inside the hollow chamber, and at least partly located in the fluidized bed zone. The internal barrier(s) have at least one opening within the fluidized bed zone, such as an underflow opening, to permit internal recirculation of material from the product zone to the feed zone, thereby simplifying reactor structure.

A process for producing substantially dry slag granules comprises adding a controlled amount of water to a molten stream of slag, and granulating the slag to produce solidified slag comprising substantially dry slag granules and slag wool. An apparatus for producing substantially dry slag granules comprises: (a) an inclined surface having an upper and lower ends for receiving and discharging the stream of slag; (b) a dispersion device at the lower end of the inclined surface for dispersion of the molten slag; (c) one or more water addition devices for adding a controlled amount of water to the molten slag; and (d) a collection area adjacent to the dispersion device for deposition of solidified slag produced by the dispersion. The quantity of slag wool produced by the process and apparatus is less than that which would be produced without the addition of water.

BioMOre describes a New Mining Concept for Extracting Metals from Deep Ore Deposits using Biotechnology. The concept is to use hydrofracturing for stimulation and bioleaching for winning of ores. The final process will consist of a so-called doublet, which is two deviated and parallel wells. In order to avoid high costs for drilling from the surface, the BioMOre approach is divided into two phases. Phase 1 will be research on the intended bioleaching process whereas phase 2 will aim at a pilot installation to demonstrate the applicability of the process in large scale including hydro-fracturing and access of the deposit from surface. The first phase should cover the intended work of the current BioMOre approach without drilling from surface. The BioMOre project aims at extracting metals from deep mineralized zones in Europe (Poland-Germany, Kupferschiefer deposit as a test case) by coupling solution mining and bioleaching. Selected sustainability indicators based on regulatory requirements of the European Commission will be applied for feasibility considerations. The main objective of the BioMOre first phase is to design and build an underground test facility for testing the concept of combined hydro-fracturing and bioleaching. The test facility will comprise a 100 m ore block, where boreholes will be drilled horizontally using standard equipment. All necessary equipment for testing different parameters of the intended bioleaching process will be established underground. The intention is to test the bioleaching process in high detail in an in-situ environment at the same time avoiding time consuming and risky permission procedures. On the other hand, the application for the permission of underground test operation must contain detailed information about monitoring of tests and all material controls. No harmful substances will remain in the mine after the tests are completed. Further to that, predictive numerical modelling of a pilot installation should be done.

A membrane treatment plant having at least two stages (53), (69), (75) arranged serially is disclosed. Each stage (53), (69), (75) comprises at least four membrane units (55) arranged in parallel, with each membrane unit (55) having an inlet (57), a feed/concentrate outlet (59) and a permeate outlet (61). Each stage (53), (69), (75) has a common inlet header (51), (67), or (73) and a common outlet header (65), (71) or (77), with the common outlet header (65) (71) of an upstream stage connecting to the common inlet header (67) (73) respectively of an immediately downstream stage. Each membrane unit (55) has an inlet flow control valve (93) connecting between its inlet (57) and the common inlet header of the stage in which it is located, and an outlet flow control valve (63) connecting between its outlet (59) and the common outlet header stage in which it is located. The inlet flow control valve (57) and outlet flow control valve (63) are operable to isolate the membrane unit (55) from its common inlet header and common outlet header to allow cleaning of said membrane unit to take place without disrupting operation of the remaining membrane treatment plant. A control system for the membrane treatment plant is also disclosed.
