Copper(II) carbonate

Copper(II) carbonate, also known as cupric carbonate or copper carbonate (CAS 1184-64-1, EC 214-671-4), is an inorganic copper salt with the formula CH2O3.Cu. It carries no assigned E-code and is classified under Salts & Minerals. It is distinct from the basic copper carbonate found naturally as malachite.

In agriculture, copper(II) carbonate functions as a seed treatment and soil amendment, releasing copper ions that disrupt fungal and bacterial cell membranes to control pathogens. In water treatment, it adjusts pH and suppresses algal and microbial growth through controlled copper ion release. Mining operations use it as a copper source in hydrometallurgical processing and flotation chemistry.

Copper(II) carbonate is supplied as a green or blue powder in technical and industrial grades, subject to REACH registration requirements within the EU. Procurement teams should confirm supplier SDS documentation and purity specifications prior to sourcing. Standard packaging formats include multi-wall bags and intermediate bulk containers.
