Antimony ochre

In the mineralogical sense of the word, antimony ochres are a loosely defined group of secondary antimony minerals of the oxide and hydroxide class.

The most common antimony ochres are cervantite, romeite, and stibiconite,[1]: 330  but their number is by no means exhaustive.

At various times, this conditional list also included other names, some of which are now recognized as incorrect or non-existent.

Antimony ochres are associated ore minerals, often more difficult to obtain antimony than the main antimonite, in addition, they are found in nature in small quantities, as an impurity or coating, which is why they are rarely used separately.

They received their name by analogy, for their external resemblance to light ochres.
