Is there a difference with our material being certifiend for organic use?

At Essential Minerals, we want to assure you that structurally, there is no difference between our Calcium Carbonate and that of our competitors. However, the differentiating factor lies in the naturally pure material we offer, free from any residues of chemicals that may be used during the milling or purification process of Calcium Carbonate.

Our ability to provide this pure material is made possible by the exceptional quality of ore from our quarry and our meticulously designed process, which eliminates the need for any purification or processing chemicals. Let us take you through our supply chain: the ore is extracted, carefully placed in individual bulk bags to protect it during transport, and stored at our New Castle Facility before processing. From there, the ore is milled and packaged to meet our customers' specific size requirements, all without the use of chemicals or grinding aids such as Propylene Glycol.

The result is a product that is naturally pure and entirely free from any additives. Our trace metals, including lead, cadmium, and aluminum, are present at ultra-low levels, while still offering an assay greater than 99% with virtually no insolubles. When you choose Essential Minerals, you not only receive a high-quality product, but also one that is free from any residues of chemicals typically used for purification or grinding aids during the milling process.

Moreover, our material is both Kosher and Halal certified. In addition to that, it has been certified as acceptable for use in organic production, adhering to the stringent standards set by the USDA National Organic Standards.

Whether you require a calcium source for your pharmaceutical or food applications, our material serves as a perfect drop-in replacement for your current supply. Importantly, it is also an excellent option for your organic applications, providing you with the purity and quality you expect from Essential Minerals.
