Solvent extraction is the most widely used method. The extraction of natural products progresses through the following stages: (1) the solvent penetrates into the solid matrix; (2) the solute dissolves in the solvents; (3) the solute is diffused out of the solid matrix; (4) the extracted solutes are collected.
Solvent extraction tests were done using 30% v/v LIX 984N at pH 1.8. The parameters of clarification and solvent extraction were the flocculant dosage (0, 58.14, 116.28, 232.56 and 348.84 g/t)...

The proposed order adding talc to Schedule 1 of CEPA 1999, also called the List of Toxic Substances, was published for a 60-day public comment period ending on July 21, 2021. Adding a substance to the list does not restrict its use, manufacture or import. Rather, it enables the Government to take risk management actions under CEPA 1999.
Solvent extraction experiments were carried out at room temperature (±27 °C) on the clarified and non-clarified solutions. The extraction was performed using 30% (v/v) LIX 984N (BASF, USA) at pH 1.8 at different O/A (1/5, 1/2, 2/3, 1/1, 3/2, 2/1, and 5/1). The mixtures were shaken until equilibrium was reached (20 min) using mechanical shakers.
