Optimization and assessment of a sequential extraction …

The main objective of our study was to develop a sequential extraction procedure for carbonate-rich samples that guarantees the quantitative dissolution of calcium carbonate in a discrete carbonate-removal step.

How to obtain calcium carbonate?

From that solution you could precipitate calcium carbonate by adding Na2CO3, via the following reaction: Na2CO3(s) + CaCl2(s) + H2O(l) ⤑ …

Towards efficient calcium extraction from steel …

Production of precipitated calcium carbonate (PCC) via carbon dioxide (CO 2) pressure-swing mineral carbonation is a potential way to utilise calcium-rich steel slag and carbon dioxide. Calcium supersaturation …

Optimization and assessment of a sequential extraction

Typical sequential extraction protocols were developed to extract from low-carbonate samples and therefore are not necessarily suitable for high-carbonate …

Preparation of High-Purity Calcium Carbonate by …

About 3% of calcium in the concrete sludge could be extracted into the filtrate in a single filtration step, and more than 95% of dissolved calcium was recovered as calcium carbonate by the …

Extracting and producing calcium carbonate.

This study aims to investigate the effects of the strength improvement of soft ground (sand) by producing calcium carbonate powder through microbial reactions. To analyze the cementation effect...
