KEMWorks laboratory is recognized in the latest issue of Fertilizer International

KEMWorks was recognized for its laboratory testing capabilities in the article “Phosphate Process Analysers” in the March/April 2017 issue of Fertilizer International. KEMWorks can perform phosphate ore characterization studies; bench-scale beneficiation studies; phosphoric acid pilot plant testing; and batch granular fertilizer production and testing. We are familiar with the latest advances in mining, mineral processing and fertilizer technology and can develop a program that can successfully turn test work into a sound commercial plant that meets your business needs.

We can perform flexible, small-scale beneficiation tests including unit operations such as crushing, scrubbing/desliming, grinding, sizing, gravity separation, conditioning, flotation, magnetic separation and more. The data obtained from bench-scale tests can be used to scale up to pilot plant testing and flowsheet design. Pilot plant testing is used to develop engineering design criteria and process operating parameters, and is used to define process efficiencies typically for determining economic process feasibility. Furthermore, the pilot plant is often used to provide bulk samples for product evaluation in the marketplace.

The purpose of the KEMWorks Phosphoric Acid Pilot Plant is to determine the behavior of phosphate rock under conditions typical of an industrial phosphoric acid plant. The pilot plant can be operated to simulate any process route including dihydrate (DH), hemihydrate (HH) and hemi-dihydrate (HDH). Data generated from the test work includes specific reactor volume, filtration rate, P2O5 recovery, acid and gypsum analysis, sulfuric acid consumption, corrosion rates, and more. We also test the reactivity and solubility of the phosphate rock to assess suitability for direct application.

Bench-scale tests can be done to make granular fertilizers such as MAP, DAP, SSP, TSP and related products including animal feed ingredients (MCP and DCP). Tests to produce MAP and DAP will determine expected grade and physical characteristics including hardness. SSP and TSP tests will also determine acid to rock ratio, rock grind as well as expected grade.
