Density & Specific Gravity:
Spodumene: Perfect cleavage in two directions
Lepidolite: Perfect basal cleavage
Petalite: Perfect cleavage in one direction
Amblygonite: Good cleavage in one direction
Tenacity:
White or colorless for most lithium ores.
Magnetism & Conductivity:
Non-magnetic.
Poor electrical and thermal conductor.
Reactivity:
Lithium ores are stable under normal conditions but react with strong acids to release lithium ions.
Additional Notes:
Spodumene is the most commercially important lithium ore due to its high lithium content (~5-8% LiO).
Lepidolite is a significant source of lithium but contains a lower lithium concentration (~3-5% LiO).
Petalite is valued for its low iron content, making it useful for ceramic and glass applications.
Amblygonite has lower economic significance but contains both lithium and phosphorus.

Safety Note:
While metallic antimony is relatively stable, antimony compounds can be toxic if inhaled or ingested. Proper handling and safety protocols are essential during processing.
Antimony ore is a naturally occurring mineral that contains antimony (Sb), a lustrous gray metalloid. The most common form of antimony ore is stibnite (Sbâ??Sâ??), which has a metallic luster and a lead-gray color. Other less common ores include valentinite (Sbâ??Oâ??) and kermesite (Sbâ??Sâ??O).

Alloying Agent
Used with lead to improve hardness and strength.
Applications:
Lead-acid batteries
Bullets
Cable sheathing
Bearings and solder
Semiconductors and Electronics.
Antimony is used in semiconductors, infrared detectors, and diodes due to its electrical conductivity properties.
Glass and Ceramics.
Used to decolorize glass and as an opacifier in ceramic enamels.
Medicine and Cosmetics (historical and niche)
Anciently used in kohl (eyeliner) and traditional medicines.

Antimony compounds are used in some paints and pigments.
Tungsten ore is a rock or mineral containing tungsten in its compound form. The ore minerals of tungsten include wolframite, scheelite, and ferberite. Tungsten is used for making many alloys. Tungsten ore deposits are predominantly magmatic or hydrothermal in origin and are associated with felsic igneous intrusions.
In nature, it primarily exists as a hexavalent cation with an ionic radius of approximately 0.68 10 m. Due to its small ion size, high electrostatic charge, strong polarization ability, and tendency to form complex anions, tungsten is commonly found in the form of [WO]. These anions interact with cations such as Fe, Mn, and Ca in solution, leading to the precipitation of minerals like wolframite and scheelite.
Nickel ores produce acidic sulfate or chloride solutions, with various processing methods employed to extract and refine nickel for alloy production. These techniques are selected based on specific industrial requirements and available information. One economically significant source of nickel is the iron ore limonite, which typically contains 1â??2% nickel.
