Orange Calcite: Healing Properties, Meanings Benefits

Orange calcite is a soft mineral, so it needs careful handling to protect it from being scratched. Avoid cleaning orange calcite with harsh substances like salt, acids, or vinegar. This risks causing a cloudy surface or even dissolving the crystal. Instead, use an air duster or a soft cloth to remove dust or dirt.

Control of dust from construction and demolition activities

Dust emissions arising from construction activities can cause nuisance both within the site and outside the site boundary (Table 1.1). Within the site, dust can cause mechanical or electrical faults to equipment, such as computers, and will increase abrasion of moving parts in plant and clogging of filters. In the surrounding environment, it can cause annoyance to neighbours by the soiling of ...
