the terms brittle , malleable , elastic , and flexible refer to what mineral
Muscovite has a perfect basal cleavage, meaning it breaks easily along one plane into thin sheets. This results in a flexible and elastic nature to the mineral, often yielding thin, transparent sheets.
Quartz is generally not considered to be malleable. It is rated a 7 on the Mohs scale of hardness. However, if it has a high gold content, it is more malleable.
Gold is a precious metal with a distinct yellow color and is very malleable and ductile. Pyrite, also known as "fool's gold," is a brassy yellow mineral with a metallic luster and a different chemical composition from gold. Mica is a silicate mineral that forms in thin, sheet-like layers and is commonly shiny and flaky in appearance, with no metallic properties like gold and pyrite.
This depends on the confining pressure, the temperature and the strain rate applied to the mineral. In general for minerals (and other materials), the lower the rate of strain, the more likely ductile or plastic creep deformation will occur. The higher the strain rate, the more likely brittle deformation is to occur. As the confining pressure increases, an objects shear strength will increase (this usually coincides with a greater depth of burial) and due to the earth's thermal gradient an increase in temperature. As the shear strength increases, brittle failure is less likely and the higher temperature means that plastic deformations or creep are more likely to occur.
For the uraninite: Brittle - Conchoidal - Very brittle fracture producing small, conchoidal fragments; data from http://webmineral.com/data/Uraninite.shtml. Any mineral of uranium has its specific properties - and we know now approx. 200 uranium minerals.
elastic
A mineral that can be bent without breaking and will stay bent is said to be malleable. This is one of the main properties of metals.
No. Diamond is the hardest mineral and it is not malleable or plastic.
Of the four, gold is the most malleable, capable of being beaten into sheets so thin that they can actually transmit light.

Mineral spirits is a parts cleaner/paint thinner. Do not apply mineral spirits to your hair. Your hair will be very dry and very brittle.
The term tenacity describes a mineral's resistance to breaking or deforming.Minerals that are ionically bonded, such as fluorite and halite, tend to be brittle and shatter into small pieces when struck.Minerals with metallic bonds, such as native copper, are malleable, or easily hammered into different shapes.Minerals, including gypsum and talc, that can be cut into thin shavings are described as sectile.Others, such as micas, are elastic and will bend and snap back to their original shape after the stress is released.Two types of micas:Muscovite Mica -- light in colorBiotite Mica -- dark in color"Applications and Investigations in Earth Science" Seventh Edition.

The mineral cobaltite, CoAsS, has a brittle fracture, and exhibits good cleavage in three directions.
