Talc particles have been found in the lungs at autopsy of both rural and urban residents as well as talc miners (IARC, 1987b, 2010). Talc particles are biopersistent in the lungs, and have been recovered in broncho-alveolar lavage fluid obtained from workers 21 years after cessation of occupational exposure (Dumortier et al., 1989).

Introduction. Talc is a naturally occurring hydrous magnesium silicate mineral (US EPA Citation 1992; Fiume et al. Citation 2015).The mineral content, morphology, and purity of talc varies based on the geological conditions under which it is created and its excavation (Drechsel et al. Citation 2018).Talc is classified into two grades.
On 12 June 2023, the European Chemicals Agency (ECHA) launched three consultations on proposals for harmonised classification and labelling: TALC (CAS 1), used as …

Talc has a Mohs hardness of 1, which is naturally crushable and has good grindability. For the fine grinding of talc, various types of Raymond mills are generally used, mainly producing 200 mesh and 325 mesh products. However, if fine grading equipment is installed, products with 500 to 1250 meshes can also be produced.

Talc, a naturally occurring mineral, is mined in many regions worldwide. Exposure to talc occurs in occupational settings during the mining and milling or processing of talc, or during the production of talc-containing products.
The agent evaluated for this volume is talc, which includes both naturally occurring mineral talc and synthetic talc. This evaluation applies to lamellar and fibrous talc forms, including asbestiform talc. Asbestiform talc is not asbestos but is a type of fibrous talc. However, talc (fibrous or not) may be contaminated with asbestos.
Talc Classification and Exposure Routes. RAC's new classification assigns talc the following hazard categories: Carcinogen 1B; H350: Suspected of causing cancer, particularly through inhalation. Specific Target Organ Toxicity, Repeated Exposure (STOT RE 1); H372: Causes damage to the lungs via prolonged inhalation exposure.
The compaction of talc on roller presses meets those demands. Due to the relative low bulk weight of fine talc, the roller presses must be equipped with a vacuum de-aeration for this purpose. Depending on the feeding material and its grain size, different throughput capacities can be achieved with a roll press of the ARC MS series. Process:
