Applications & Service of Golden Lime Plc.
- Applying quick lime and Dolime
- Both of quick lime and Dolime are used in the ironmaking process to produce the slag, which removes impurities from the iron ore while making liquid pig iron and do the preventive refractory of Electric Arc Furnace (EAF). Quicklime and Dolime normally are added to iron sinter and pellets to add flux and promote agglomeration in your products.

Civil Engineering
Key considerations & Benefits
Key Considerations
Mill limestone is used in asphalt mixtures as conventional filling material. The presence of calcium ions at the surface results in good adherence of bitumen to this fine filling material, which leads to reduced stripping and less moisture sensitivity.
Benefits
Mill limestone in the mix will increase the durability of asphalt mastics and asphalt concrete.
- Superior hydrated lime, mixed with sand and cement to produce very smooth masonry mortars, plasters and renders.
Mortar & Cement
Key considerations & Benefits
Key Considerations
Hydrate has been used as a primary ingredient in masonry mortars for centuries, and is still used in both historic and contemporary applications. Mortars made with hydrated lime and cement exhibit superior workability balanced by appropriate compressive strength, combined with high flexural strength, low water permeability and superior bond strength.
Benefits
Studies have compared the performance of cement-hydrated lime mortars with masonry cement mortars. Cement- hydrated lime mortars have shown higher bond and shear strength and lower water leakage.
- Our product is engineered milled limestone for all types of ready-mix and precast concrete.
Concrete
Key considerations & Benefits
Key Considerations
Better pumpability is achieved to the presence of numerous microfines below 2?m, which helps to increase the rheological behavior of mixes. These microfines also result in a product with consistent behavior in water absorption, which is highly valued for self-compacting concrete.
Benefits
The ready-mix product is recommended for use in architectural concrete, thus minimizing the use of coloring agents. Besides this technical advantage, it can partially replace cement in the mix, once certified according to the Equivalent Concrete Performance Concept in line. This enables producers to make significant cost savings and carbon footprint savings.

- Understanding Your Market Needs
- PCC, a white powder with specific crystalline form and size, is produced by reacting milk of lime with carbon dioxide. Normally milk of lime is produced by slaking quicklime. The particle size of the slaked lime is a key parameter for the precipitation of calcium carbonate.
- An even precipitation process allows good control of the crystallization and particle size of the MOL. Thus lime reactivity is key to achieving the required particle size and shape of PCC, as well as the stability of the process.
- The whiteness and brightness of PCC are very critical, especially for office (white) paper manufacturing. Here, the impurities level must be well controlled, especially the iron oxide and manganese oxide.
- Other components, like silica or alumina, are considered to be impurities for the final PCC, as they affect the PCCs properties.
- Solutions to Meet Your Needs
- Golden Lime Plc provides special high-purity quicklime (different lump sizes) for PCC manufacturers, with consistent and appropriate quality and reactivity.
PCC (Precipitated Calcium Carbonate)
- Pulp & Paper (with quick lime)
- Understanding Your Market Needs
- In the paper and pulp industry, lime is mainly used in the Kraft process. Here lime is used in causticization the recovery of sodium hydroxide by the reaction of slaked lime Ca(OH)2 and sodium carbonate Na2CO3. This reaction generates sodium hydroxide (NaOH), which is reused in the pulp process and calcium carbonate (CaCO3.). This calcium carbonate (as a mud) can be calcinated in the local lime kiln to generate quicklime, which is then slaked and reused in causticization.
- In pulp and paper plants, lime can be used for many other purposes. They include water treatment, pH neutralisation, and flue gas cleaning, and so on.
- The reactivity of lime and CaO content must be the best possible, in order to facilitate a smooth slaking process and the best yield in sodium hydroxide recovery.
- Solutions to Meet Your Needs
- Golden Lime Plc supplies high quality lump lime for this application.
- High quality quicklime can help to reduce this NPE loading, and our technical support can assist with process optimization to reduce the negative effects. We can meet your supply demands during planned outages and even many unplanned outages.

Agriculture
- Understanding Your Market Needs
- To produce calcium compounds, lime products are used mainly as a source of calcium to make a wide diversity of chemicals. Among them are bleaching powder, calcium phosphate, calcium chloride, calcium soaps, calcium lactate, calcium nitrate, calcium citrate, and many others. These chemicals are used in various industries, such as fertilizers, plastics, and food, etc.
- In the chemical industry, lime is also necessary to produce alkene oxides, trichloroethylene for degreasing, magnesium hydroxide for refractories, oil additives for lubricant and greases etc.
- Lime product provides the calcium element that will be embedded in the final chemical compound. Lime property will have a direct impact on the reaction process and on the quality of the final product.
- This is especially true, because the calcium available to the reaction must be as high as possible to get the maximum yield from the lime. Purity is also key to guaranteeing the quality of the final product.
