Our Product Portfolio

Quicklime

Micronised Minerals Fine Quicklime is a high quality calcium oxide product manufactured to a very fine grain size (typically less than 150μm), maximising the availability of CaO for chemical processes.

Quicklime or Burnt Lime chemically known as Calcium Oxide (CaO), is a highly reactive chemical with variety of uses in the mining, industrial water treatment sectors as well as Civil sector. Quicklime is most commonly used for its ability to stabilise pH, soften water, stabilise bio-solids, and precipitate nutrients.

Quicklime for Mining sector

Quicklime is mainly used by mining industry to treat runoff and process waters from coal mining, metal mining and non-metal mines. Quicklime used with properly designed slaking plants helps to neutralise acids from mining waters and precipitate metals and non-metals. 

Micronised Minerals has supplied individual clients up to 20,000 tonnes per annum of Quicklime utilising in-house designed innovative Handling and Storage Solutions.

Quicklime for Civil sector

Quicklime has important applications in construction operations. It can be used for Road/Soil stabilisation; dry-up wet soil at construction sites and improve soil-workability and short-term strength.

Road / Soil Stabilisation – When adequate quantities of Quicklime and water are added, the pH of the soil quickly increases to above 10.5 which enables the clay particles to break down. The chemical reaction forms cementitious products that forms the matrix that contribute to the strength of lime-stabilised soil layers. The matrix is permanent, durable and significantly impermeable, producing a structural layer that is both strong and flexible. 

POTENTIAL USAGE

  • Acid Water Treatment using specially designed Slaking Plant

  • Acid Sulphate Soil Treatment

  • Soil Stabilisation

Packaging options: 500-1200 kgs. Bulker Bags and Bulk Tankers

Hydrated Lime

Micronised Minerals Hydrated Lime (slaked lime), is a high quality calcium hydroxide product manufactured to a fine grain size which maximises the availability of [Ca(OH)2] for chemical processes.

Calcium Hydroxide [Ca(OH)2], also known as Hydrated Lime, is a fine, odourless white powder commercially produced by reacting Quicklime with sufficient water. It is used in many applications, including food preparation, water treatment, soil stabilisation and can be added to water to produce Milk of Lime.

Hydrated Lime for Government sector

Hydrated Lime is vital to municipalities, it is used for potable water softening pH, removal of heavy metals and impurities from drinking water.

Hydrated Lime for Cattle Industry

Hydrated Lime is used as a binder in cattle-feed products and as a Calcium supplement for animal feed products. Hydrated lime is a highly cost effective method for treating sewage sludge and animal waste from concentrated animal feeding operations.

Hydrated Lime for Civil sector

Hydrated Lime is used as soil stabiliser due to its properties to set-up an alkaline environment in presence of water. It reacts with pozzolans (materials containing reactive silica and alumina) present in the pavement material or subgrade and the hydrates complexes formed with chemical reaction dramatically reduce soil plasticity; increases its workability and improves its compaction characterisitcs.

Calcium Carbonate

Calcium Carbonate with NV>99%

Calcium carbonate is a primary component of Agricultural lime, also known as Ag-lime which is used for neutralising acidic soil and to enhance soil quality. Calcium carbonate when added to soil, acts as a rich source of calcium for plants and increases the pH and water-retaining capacity of acidic soils. Also, it enhances the consumption of essential plant nutrients like nitrogen, phosphorus and potassium in acidic soils.

Micronised Minerals Calci Flour is a high quality Calcium Carbonate product ground to mean average particle size of 18 microns. It is specially formulated to maximise the ENV (Effective Neutralisation Value) creating a balancing agent for low pH soils.

Calcium is the “King of Minerals” that releases the strongest growth energy for plants, which carries many other nutrients and micro-nutrients into the plant during uptake. Calcium is vital for strong plant cell structure, fruit quality and disease resistance at optimum levels. Micronised Minerals Calci Flour is the perfect product for all fruits and vegetables, high quality hay and healthy livestock.
