Lime Milk Handling & Dosing for Mining pH Control

Lime milk plays an important role in mining and mineral processing wherever pH needs to be raised, stabilized, or controlled. It is commonly used in concentrating plants, acidic effluent neutralization, process water treatment, and other applications that depend on reliable alkalinity. Yet lime milk is not a straightforward liquid reagent. Its suspended calcium hydroxide particles make it abrasive, prone to settling, and capable of forming deposits that disrupt pumping and dosing.

The exact challenge depends on the application. In some operations, the priority is keeping lime milk concentration consistent from preparation to injection. In others, it is preventing sedimentation, scaling, and wear from undermining pump performance. Line routing, shutdown behavior, maintenance access, process demand, and regional operating conditions can all influence whether the system delivers a predictable dose or becomes a recurring source of intervention.

SEEPEX progressive cavity pumps convey abrasive lime milk at controlled volumetric flow through fixed-shape cavities. This supports accurate dosing even when viscosity or solids content changes within the selected duty. Low operating speed, self-priming behavior, reversible flow, no seal water requirement, and maintenance-friendly access help keep lime milk systems available under demanding conditions. The objective is clear: Control pH, not pump problems.

Reliable Lime Milk Handling Supports Reliable pH Control

Across these pages, the same practical relationship becomes clear: pH control depends on more than the amount of lime milk calculated for the process. The slurry must remain consistent, flow through a suitable line arrangement, and reach the injection point at a controlled rate. If sedimentation, deposits, abrasion, or maintenance interruptions change that delivery, the process receives a different chemical input than the control system expects.

SEEPEX progressive cavity pump technology supports reliable lime milk handling through controlled volumetric flow and pump-speed-based adjustment. Depending on the selected solution, features such as Rotor Joint Access and Drive Joint Access can simplify service and reduce disruption when maintenance is required.

A reliable lime milk system connects slurry preparation, storage, pump selection, line design, instrumentation, and maintenance into one predictable dosing process. That is the difference between reacting to recurring slurry-handling problems and keeping pH control focused on the mining process itself.
