Mining operations can generate several different types of waste streams:

• Sump pits
• Tailings
• Coal ash pits
• Wash slime waste
• Minerals refinement fractions

Often these waste streams need solidification and binding of free liquids in order to be shipped to a licensed disposal facility. Conventional sorbents sawdust, lime kiln dust, corn cob – normally expands the waste volume by 50-100%.  This greatly increases disposal costs in terms of higher transportation costs due to more loads and, of course, higher landfill disposal fees.Use of WASTE LOCK® superabsorbent polymers allows waste generators to meet EPA 9095 (Paint Filter Test) requirements but expands the waste volume by LESS THAN 1% !
