Appendix 4 Properties of oil shale waste rock after separation .. 55 Appendix 5 Properties of waste rock aggregate in accordance with GOST.. 56 Appendix 6 Bulk Table 3 Types of crusher and reduction ratio [11] .. 19 . 8 1 TERMS Aggregate granular material used Oil shale waste rock (limestone, marlstone or dolostone) is produced during extraction as reject material from separation plant and material from crushing and sizing operations in aggregate production. Major part of waste rock from opencast mine is used for mining site restoration. Waste rock shale is separated from run of mine in separation plant. The waste rock extracted in mining or separated in plant is usable in civil engineering and road building. Some physical properties of waste rock aggregates depending on content of oil shale. Keywords Oil shale, waste rock, aggregate, selective crushing Introduction for oil shale mining waste rock is the impact crusher. Grains of aggregate are crushed against crusher parts and against each other, producing good cube shaped product. Oil shale waste rock (limestone, marlstone or dolostone) is produced during extraction as reject material from separation plant and material from crushing and sizing operations in aggregate production. Major part of waste rock from opencast mine is used for mining site restoration. TUT Department of Mining pilot unit for test ing oil shale and oil shale waste rock: Oil shale waste rock with axle bucket crusher on w heel loader . 0. 10. 20. 30. 40. 50. 60. 70. 80. 90. 100. crusher and sizer can b e used for decreasing losses . and increasing yield. which has several benefits, requires careful selection of oil shale waste rock aggregates and other carbonate Dec 26, 2013 Multiquip crushing shale with Impact crusher for road base, southern highlands NSW, Australia. The main methods for selective extraction of limestone, oil shale and phosphate rock have been selective blasting, bulldozer and excavator ripping and cutting by surface miners. Selective crushing has been achieved by axle crusher and separation by jigging. All methods have shown promising results for changing the waste rock balance in the product. Drum screener and hammer crusher for dry selective oil shale separation. Losses are closely related to backfilling and waste rock usage. Much smaller sections include production of oil
