arsenides

Also, the arsenides are pretty important in their diet.

Doctor’s Orders Diane Duane 2000

There are cases when gold is contained in ores in what is known as a perfectly "free" form -- that is, there is an absence of all sulphides, arsenides, etc. -- when it is not practicable to extract it either with the ordinary forms of quicksilver amalgamation of or any process of chlorination, without first roasting.

The fissures were mineralized with copper sulphides and arsenides, iron sulphides, and locally with zinc sulphide and manganese carbonate, -- all in a matrix of quartz.

The Economic Aspect of Geology 1915

Native silver and various silver sulphides, arsenides, and antimonides are associated with minerals of cobalt, nickel, bismuth, lead, and zinc, in a gangue of calcite and some quartz.

The Economic Aspect of Geology 1915

The silver ores of the Cobalt district of Ontario (pp. 234-235), containing nickel and cobalt arsenides, produce considerable arsenic.

The Economic Aspect of Geology 1915

The principal ore minerals are the nickel sulphides and arsenides

Our Northern Heritage 1906

More recently the auriferous-arsenic ores of Temagami were made known, and lastly a discovery has been made of the series of cobalt nickel arsenides and silver, which are unique, so far as known, on this continent, and are paralleled by deposits only in Saxony and adjacent regions of continental Europe.

Its chief ores are smaltite and cobaltite, which are arsenides of cobalt, with more or less iron, nickel, and copper.
