Malachite also has a specific gravity of 3.6-4.0, which is relatively heavy for a non-metallic mineral. It is also known for its effervescence in acid, which means it will bubble and fizz when exposed to acid. Malachite has been used for a variety of purposes throughout history. In ancient Egypt, it was used as a pigment for paint and cosmetics.

As the initial MG dye concentration increase from 20 mg/L to 100 mg/L, the amount of MG dye adsorbed at equilibrium increase from 0.39 mg/g to 3.92 mg/g. The higher initial dye concentration give a stronger driving force to overcome the mass transfer resistance between the solid phases and aqueous solution [2].

Copper Ore Concentration. Most copper ores contain only a small percentage of copper. The remainder of the ore consists of gangue of no commercial value. Gangue from copper mining typically contains silicate minerals and oxides. In some cases these tailings have been retreated as the technology for recovering copper has improved.

The Malachite is a Hardmode dagger that is dropped by The Plaguebringer Goliath. When used with its primary fire (left-click), it will rapidly throw kunai that are affected by gravity and stick to enemies or tiles, exploding after a brief delay. When used with secondary fire (right-click), it will fire a single larger kunai that pierces once and explodes upon hitting the next enemy or tile.
