Mineral deposit Iron deposits Britannica

Manganese deposits similar to Algoma-type iron deposits are widespread. Generally considered to have formed as a result of submarine volcanism, most are too poor to mine, but, where weathering has caused secondary enrichment (discussed below), small but very rich ore deposits have formed. Such deposits are mined in Brazil, Mexico, Gabon, and Ghana.
