What are the key production technologies for magnesium carbonate and their cost implications?

The choice of process directly impacts product purity and cost structure. As environmental regulations tighten, the lime method's calcium chloride waste stream becomes a liability. Producers that can valorize by-products or switch to cleaner routes will gain a cost advantage, especially for high-purity grades used in lithium battery applications.

How is China's magnesium carbonate market structured by product type and downstream application?

The light versus heavy grade split is critical for pricing. Light grade commands a premium due to higher purity requirements in food and pharma, while heavy grade is more commodity-like. Watch for capacity shifts in Hebei and Jiangsu, where leading producers are investing in cleaner, continuous processes that could tighten supply of high-purity material.

Overview

Magnesium carbonate (CAS 546-93-0) is a white, odourless inorganic compound with a molecular weight of 84.31 and a density of 3.05 g/cm³. It is a multifunctional material valued for its thermal stability, dispersibility, and plasticity, serving across pharmaceutical, food, and industrial sectors.

Pharmaceutical: acts as an antacid, anti-ulcer agent, and mild laxative, neutralising stomach acid to relieve gastric discomfort.
Food: used as a flour improver, bread leavening agent, and magnesium supplement in bakery goods, jellies, and ice cream.
Rubber & plastics: serves as a reinforcing filler that improves tensile strength, surface smoothness, heat resistance, and toughness.
Industrial: applied in ceramics, fireproofing materials, inks, paints, and as a drying agent in products like gymnastics chalk.

China's production landscape is fragmented, with many small workshops lacking consistent quality standards, though larger producers are adopting advanced calcination and carbonation routes. Light and heavy grades dominate output, with high-purity material increasingly demanded for specialty applications.

Key domestic producers:
Jiangsu Zehui Magnesium – analytical and high-purity grades via advanced production lines.
Other regional producers – light and heavy industrial grades for rubber and construction uses.
