Daniels Fabrication also undertakes the fabrication of plate work including chutes, hoppers, sumps, and conveyor components including trusses (up to 60 m span), conveyor tubes, channel pans, bents (up to 75 m height), head, tail and take up frames. Many other major processing equipment can be manufactured by our sister company BGTG.

6. DANIELS’ LONG HISTORY USA THE DANIELS COMPANY’S LONG HISTORY • Engaged in coal preparation project since 1950s • The only company engaged in coal processing & material handling systems to still be in business over 60 years in USA.

7. DANIELS’ CAPABILITY USA CAPABILITY: • Engineering, Procurement and Construction of coal preparation plants and coal handling facilities • Upgrading existing CHPP to improve clean coal recovery efficiency, eliminate bottlenecks and/or coal processing capacity • Consulting services – Performance evaluation of coal preparation facility to optimize clean coal recovery efficiency • Supply full line of CHPP equipment

8. DANIELS’ ADVANTAGES USA DANIELS’ ADVANTAGES OVER ITS COMPETITORS • The Daniels Company’s long history has accumulated significant experience of CHPP design and construction • Over 180 coal preparation plants and coal handling facilities have been built by The Daniels Company in USA and overseas since it was founded. • Coal preparation plants were built with capacity up to 10 MTPA and coal handling facilities were built with capacity up to 30 MTPA. Long distance conveyor system were built with trusses up to 60 meter and bents up to 75 meter height

9. DANIELS’ ADVANTAGES USA DANIELS’ ADVANTAGES OVER ITS COMPETITORS • The Daniels Company always provides its clients with plant performance guarantees to design & supply the most efficient process circuit for each size fraction of raw coal to its clients. This generates maximum benefits to our clients at relative low cost. This has allowed The Daniels Company to survive from 1950s until present time while its competitors have disappeared. • Historically, preparation plants designed and built by Daniels have met and exceeded on time, on budget and on performance required by the customers.

10. DANIELS’ ADVANTAGES USA DANIELS’ ADVANTAGES OVER ITS COMPETITORS • The Daniels Company is experienced in the following various process circuits, which have been incorporated in its plants over a period of several years, in United States, Canada, Colombia and India. • Coarse circuit (H.M. Vessel, H.M. cyclones, and Jig • Small coal circuit (H.M. cyclones, W.O.C & combination) • Fine coal circuit (2-stage W.O.C, W.O.C/Spiral combo, spiral, H.M.C) • Ultrafine coal circuit (Conventional cells, column cells, Jameson cells, stack cells, floatair cells, jet-type flotation cells and etc.) • 3-product HM cyclone technology from BGTG is most likely a good fit for processing India coals.

11. DANIELS’ ADVANTAGES USA DANIELS’ ADVANTAGES OVER ITS COMPETITORS • The first Daniels H.M. Vessel was produced from The Daniels Company. Currently there are hundreds of Daniels H.M. Vessels operating in the whole world (China, Russia, Poland, India, Canada, USA, Indonesia, Mexico). The world largest H.M. Vessel, built by The Daniels, is currently operating in a Murray Energy plant in the USA. It has a feed capacity of 900 tph of coarse coal and 400 tph of reject material.

12. DANIELS’ ADVANTAGES USA DANIELS’ ADVANTAGES OVER ITS COMPETITORS • The Daniels Company is the only company in USA who is designing and constructing CHPP and also manufacturing part or most of CHPP equipment, such as HM vessels, HM cyclones, vibrating screens, sieves, centrifugal dryers, flotation cells and etc. • The Daniels Company’s staff always keeps up with the latest developments in coal processing and coal handling technologies.

13. Merging with BGTG USA • The Daniels Company (USA) • Beijing GT Group • (China) • +550 Plants • +180 Plants • & Coal • handling • facilities GT GLOBAL

14. DANIELS’ ADVANTAGES USA DANIELS’ ADVANTAGES OVER ITS COMPETITORS • After merging with Beijing Guohua Technology Group, The Daniels Company can now access manpower & equipment from combined resources. This enables The Daniels Company to offer competitive cost CHPP to its clients with high quality and efficient operations that can be managed by The Daniels Company. • Utilizing the well recognized 3-product H.M. cyclone technology enables The Daniels Company to offer its clients with optional technology to further improve clean coal recovery. Currently about 1/3 of China washed coal is going through +550 coal plants built by BGTG. • The 3-product HM cyclone is particularly suited to process Indian coals, which usually require high separation density (>1.8 kg/L). The 3-product cyclone can provide in one circuit and one-step the ability to produce both coking coal and thermal coal.

17. ADVANTAGES OF NEW HM PROCESS OVER TRADITIONAL PROCESS USA FOR INDIAN COKING COAL • The new HM process with non-desliming significantly simplifies HM process using less equipment (without desliming screens, hydro-cyclone, spirals, TBS and etc.) and smaller plant space required, which results in lower capital investment • Gravity-fed reduces secondary coal fines generation considerably • Lower operating cost due to simple process, less equipment & much higher separation efficiency than traditional processes • Using low single density HM suspension to achieve stable high separation density • Higher clean coal yield due to higher separation efficiency compared to traditional HM process especially for high ash and difficulty-washing coal requiringhigh separation density

18. ADVANTAGES OF NEW HM PROCESS OVER TRADITIONAL PROCESS USA FOR INDIAN THERMAL COAL • The new HM process with non-desliming also significantly simplifies HM process using less equipment • Gravity-fed reduces secondary coal fines generation considerably • Lower capital & operating cost due to simple process, less equipment & higher separation efficiency • Using low single density HM suspension to achieve stable high separation density easily as high as 2.3 to produce high ash reject (pure rock).

19. ADVANTAGES OF NEW HM PROCESS OVER TRADITIONAL PROCESS USA 2. Gravity-fed reduces secondary coal fines generation considerably Industrial plant tests indicate: The secondary slime generated during washing process with gravity-fed H.M. cyclone is 5~7 percentage points(in total feed) less than that produced during process with pressurized feeding cyclone. This is very important and beneficial to the design of thermal coal plant. Test at Linhuan Plant: Difference of Amount of -0.5 mm Fines between Gravity-fed & Pump-fed ※Each cyclone feed rate: 302 t/h

20. ADVANTAGES OF NEW HM PROCESS OVER TRADITIONAL PROCESS USA 3. Lower operating cost due to simpler process, less equipment, & much higher separation efficiency (higher centrifugal force and lower separation size limit) than traditional processes • Higher centrifugal force: HM suspension feed pressure is double the traditional HM process (17 times of cyclone diameter instead of 8 times) • Lower separation size limit: effectively separate coal particle size down to 0.25 mm in the 3-product cyclone and down to 0.1 mm in fine coal HM cyclone Coal Size Fraction Epm Value Throughput Capacity > 0.5 mm Up to 1300 t/h, (I) 0.02-0.025 (II) 0.025-0.045 0.5~0.25 mm Up to 1300 t/h, 0.099kg/L 0.1~0.074 mm 0.08 kg/L No ultrafine magnetite needed
