An acetylene manufacturing plant had a pond of hydrated lime that needed to be removed. Gilmour & Company was hired to study the potential market for the lime and logistics to supply the market. We found a customer and helped negotiate a contract between the producer and end-user, supplied the equipment and labor to recycle the lime from the pond, and coordinated the logistics for transporting the material.

The pond contained over 1400 tons of lime which we processed into a marketable slurry. The project was completed in less than six months and saved the company massive disposal costs and allowed them to move forward with plans to relocate.

A hazardous waste disposal company had been receiving waste acid from various producers and treating the material in ponds. Since their permanent acid neutralization system had not been completed, a temporary system was needed. Lime was chosen as the neutralizing agent because of its relatively low alkalinity cost and ability to precipitate heavy metals.

Site engineers, with input from Gilmour & Company, developed a system consisting of a portable lime slaking unit (capable of slaking up to 100 tons/day of quicklime), portable Baker tank containers for storage of the lime slurry, and a two-stage acid neutralization system. Gilmour & Company recommended how to handle and store the lime slurry, provided the slaking system and related equipment, and delivered the quicklime on a scheduled basis.

A mine reclamation project in a remote location in Canada required a lime slurry source for a pond pH control. Gilmour & Company worked with the mine reclamation specialists, operations personnel and consulting engineer and the lime supplier to provide a portable lime slaker and a portable lime silo. The silo was required to alleviate problems in getting lime to the remote site.

The installed system allows the mine the capability to produce thousands of gallons of lime slurry for pH control at several pond locations.

A mine in Utah needed a temporary system to back-up existing lime slakers that needed maintenance. Working with lime suppliers, Gilmour & Company provided a portable lime slaking system to allow the mine to continue to operate while rebuilding their existing equipment.

Heap Leach Mine Treats Water Runoff

A heap leach mine in Nevada needed to treat the water runoff into an abandoned pit. Gilmour & Company provided a portable lime slaker and assisted the mining company in applying the lime.

A wood product company in Washington State periodically needed to treat organic waste sludge for their plant. Gilmour & Company provided alkaline admixture used in treating this sludge for disposal in their landfill.

An aluminum mill in Washington was using 15-30 tons of quicklime per day to treat fluoride wastes. The existing slakers required the usual high maintenance and operator attention and were running at a low slaking efficiency rate. Acting on recommendations by Gilmour & Company, the mill converted one of the two overhead dry lime storage silos into a storage tank for a by-product lime slurry which Gilmour supplied on a daily basis.
