What it is Filled
Class 2 in the ninth edition of the Nickel-Strunz mineral classification comprises sulfides and sulfosalts together with related minerals such as selenides, tellurides and arsenides; examples include pyrite, galena, sphalerite and chalcopyrite, and many members are important metal ores; sulfur-bearing members include minerals with sulfide ions and minerals such as pyrite with disulfide units.
Why it exists Filled
Let an agent handle sulfide minerals by composition, group, properties, occurrence and hazards.
Distinguishing features Filled
- Class membership includes sulfides, sulfosalts and related minerals such as selenides, tellurides and arsenides.
- Sulfur-bearing members can contain sulfide ions or disulfide units, as in pyrite.
- Members are often metallic and dense.
- Many members are major ore minerals.
- Oxidation of sulfide minerals can form acid drainage.
What robots and AI may and may not do Filled
Must not
- Advise handling or heating sulfide minerals without warning of toxic fumes or dust.
- Help mine or trade minerals illegally or from conflict areas.
- Downplay pollution from sulfide waste.
Only with a human decision
- Approving disposal of sulfide-rich mine waste.
May
- Identify sulfide minerals and report their properties and associated metals.
- Explain their role as ores and in acid mine drainage.
Moral aspects Filled
- Sulfide mining waste acidifies rivers for generations.
- Mining communities bear the harm while profits flow elsewhere.
Who is affected
- Mining communities
- Workers
- Rivers and ecosystems
Owners Filled
Steward
The mineral rights holder, usually the state or landowner under mining law.
Master systems
- Mining cadastres
- Mineral databases such as the IMA list of minerals

What else AI and robots need to interact with it Filled
Identity and identifiers required Filled
- Vercy registry: vr.tr.sulfide-class-of-minerals
- Wikidata: Q927407 (https://www.wikidata.org/wiki/Q927407)
- Strunz class: 2 (sulfides and sulfosalts) classification
- IMA mineral symbol: approved symbols mineral names
Direct properties required Filled
- Mineral density: g/cm3 - Determine density from specimen mass and volume because values differ substantially between mineral species.
- Scratch hardness: Mohs scale - Determine hardness by comparison with reference minerals on a suitable surface because the class has no single characteristic hardness.
- Electrical resistivity: ohm m - Measure resistivity under specified temperature and crystal orientation because conductivity varies with composition and structure.
Recognition required Filled
- Metallic lustre
- High density
- Group names such as thiospinel or linnaeite group
- Often metallic, dense, brassy, grey or black crystals.
Capabilities and actions required Filled
- identify by properties
- classify under Strunz or Dana
- assess ore deposits
- manage acid mine drainage
Hazards and failure modes required Filled
- Acid mine drainage
- Toxic metals such as arsenic and mercury
- Dust in handling
Standards and interfaces required Filled
- IMA mineral nomenclature
- Mining waste and water discharge regulations
Context of use required Filled
- Major ores of copper, lead, zinc, nickel and other metals.
- simple sulfides such as galena
- disulfides such as pyrite
- thiospinels
- tellurides and selenides (related)
- sulfosalts
