The quality of our products has been of great pride to us during all this time. Thanks to its calcination process the calcium oxide we manufacture has certain features, which differentiates it from the rest of limes in the market. With a high level of reactivity it is ideal for certain industrial processes like: neutralizer, fluxing material, causticizer, lubricant, drier, for cementing, absorbing, precipitating, as a disinfectant, a waterproofing and, of course, as a raw material.
Type of industrial applications
The excellent quality of our products enables its application in the more diverse industries.
In industrial paints
AL FRESCO AND DRY PAINTS. Both procedures consist in the direct application of the paint on a previous lime underground.
WITH CASEIN. It consists of mixing calcium hydroxide with casein, giving it a hard casein compound and lime of high resistance to atmospheric agents.
SATIN WHITE. It is obtained by treating aluminium sulphate, free of iron and finely grounded, with hot lime milk.
TITAN WHITE. Treating the ilmenite with carbon and calcium hydroxide you get iron and from the bottom ashes of this process, you obtain a titanium dioxide with a very high purity rate.
VARNISHES. Generally hydrated lime is used in resinous-oil varnishes acting as a neutralizer of the acid in the resin, clarifying and hardening the varnish.
In the rubber industry
Calcium oxide is used to increase the speed of vulcanization and as an accelerator and to eliminate, at the same time, the excess of moisture in the rubber.
In the fusion of glass
Within the kilns to melt glass, the use of lime instead of limestone accelerates the fusion of glass improving the shine and colour of the finished product. This contributes to saving fuel, whereas the quality and production of glass are improved.
In the paper pulp manufacturing
This industry is one of the biggest consumers of calcium oxide. Lime absorbs the CO2 of the carbonate soda to regenerate the soda, an expensive reagent and difficult to manage in the environment.
Lime finds other secondary uses in this industry as a whitening agent and in the wastewater treatment.
In the leather tanning industry
This is one of the oldest applications. The lime milk baths, where the in-transit leather lies, allow controlling hair extraction and the swelling hereof before the tanning of the leather. All the weakened hair gets fused into the destruction of the mucous membrane layer, which as a result, splits skin and dermis. Afterwards, the dermis can be separated easily from the hair using a tool.
In the production of acetylene
This gas, used in welding, needs the production of calcium carbide. This material is created by putting lime in contact with coke coal at high temperatures in special kilns.
In the iron industry
This industrial sector needs large quantities of unslaked lime in the shape of lumps with a constant quality, high reactivity and low contents of sulphur, phosphor and residual CO2.
Lime plays a role in the fusion of cast iron and as a refining agent of the steels in the elimination of impurities for its desulphurization and dephosphorization characteristics, as well as for the setting and liquefier of the skimming, retaining the typical impurities like silicate, phosphor, sulphur and to a minor degree, carbon and manganese.
Lime works as a lubricant in the pulling of wires, as well as in the melting of ingots and makes its removal easier.
The slagging, desulfurization, dephosphorization, its heat resistance and its protection are entrusted to lime.
In the process of floatation lime is used to separate the impurities of the different metallic salts, as well as to regulate the pH of the wastewater used all along the production process.
As fluxing material in the melting of copper, lead and zinc.
It is also used in the production of magnesium and in the production of aluminium as slag former.
Micronized calcium hydroxide with a high content of free Ca (OH)2 are required.
Lime is used in the recovery of metals like: copper, alumina, magnesium, zinc, lead, gold, silver, uranium, etc...
In the regeneration of mercury lime is used to eliminate sulphur. It is used as well in the recovery of gold and silver in order to get the pH under control.
In the agro-food industry
SUGAR PRODUCTION. Big quantities of quicklime with low contents in silica and magnesium are consumed with the aim of precipitating the mineral or organic impurities which can be found mixed within the saccharose. Lime is used in the production of beet and cane sugar.
BREWERY. Lime is associated in the preparation phase of formation water by absorption of surplus CO2.
OYSTER FARMING. Lime helps in cleaning the supports of nascent oysters and facilitates its development.
FISH FARMING. For recalcification of lakes, ponds and rivers, lime brings the calcium necessary for the maintenance of the food chain while balancing the natural environment.
FOOD. Lime is added directly on the pasta of Mexican "tacos" judiciously balancing the acidity of very spicy seasonings.
In the pharmaceutical industry
DENTAL CARE PRODUCTS. Slaked lime is used for its disinfectant properties and their contribution to calcium.
MEDICINES. In numerous medications, precipitated calcium carbonate derived from lime (easily assimilated by the body) is associated with the active molecules.
THE COSMETIC INDUSTRY incorporates lime for its basic properties in depilatory products.
GELATINE PRODUCTION. Gelatine is produced from beef, cow and pig bones cleaned of flesh, fat, dried up and cut into pieces. First, hydrochloride acid is applied in order to separate the organic contents from the mineral contents. Afterwards a lime milk is applied to the organic elements during 30-60 days with the aim to get collagen through hydrolysis.
