Chromium (Cr) ore deposits are typically found in complex geological settings and can occur in various types of rock formations. The major types of chromium ore deposits include: 1. Podiform deposits: These are the most common type of chromium ore deposits and account for …
The mine employs both surface and underground mining methods. Production started in 1950, and the overall output of the mine was considered to be of medium size. The mining operations at the Zeerust Chromium Mine cover an area of 750.00 hectares (1,853.29 acres), with four distinct surface and underground workings.
The relationship between mining and digital is growing stronger and more reciprocal. Mining products produce the electronics that digital technologies use. And digital solutions and technologies hold the key to making mining construction and operating processes more cost-effective and environmentally sustainable.
Chromium has long been recognized as a toxic, mutagenic and carcinogenic metal. It is toxic to microorganism, plants, animals and humans. Chromium exists in environment in two stable forms: Cr(VI) and Cr(III). Cr(III) is less toxic and insoluble, while Cr(VI) is extremely toxic and highly soluble. Chromium is used in many industrial …
The chromium removal efficiency increased as the dosage increased. The chromium removal was minimum at 49.3 % for a dosage of 0.15 g/l, and maximum removal was 68.91 % at 0.5 g/l.
