The Basics of Nonferrous Metallurgy

Mg-Al-Zn Alloys: Part One

Magnesium alloys are widely, and increasingly used in some key industrial sectors such as the automotive and aerospace industry and can be particularly associated with providing possibilities for meeting ever increasing light weighting requirements.
It is possible to increase the application of Mg alloys through alloying with other elements such as aluminum, zinc, copper, manganese, which will provide much improved mechanical performance of the material where required.

Mg-Al-Zn Alloys: Part Two

Magnesium alloys are widely, and increasingly used in some key industrial sectors such as the automotive and aerospace industry and can be particularly associated with providing possibilities for meeting ever increasing light weighting requirements.
Key to wider the application of magnesium alloys are the relative advancements that can be gained through a range of process improvements which can have a direct impact on microstructure and surface microhardness to improve overall material performance.

Minor Metals & Mineral Conservation an Overview: Part Five

The recycling of minor metals and minerals is an important factor of the overall conservation strategy and can be separated into two developing areas. Recycling of end of life wastes has a number of key pre-treatment steps which are followed by scrap dealers including collection, sorting, labeling and recovery.
Recycling of mixed metal scraps presents some other obstacles and it is therefore necessary to follow some clear guidelines to ensure the processing of such materials is handled correctly and efficiently.

Minor Metals & Mineral Conservation an Overview: Part Four

For controlling metal depletion the drainages are to be judicially reduced at various production stages and at the same time the impetus on collection of spent EEEs (electrical and electronic equipment) should be maximized by the sellers to achieve the highest collection efficiencies.
The complex metals present in EEE are not only valuable but also rare and the conservation of these metals is extremely necessary. The main problem associated with PCBs of all EEE is the recovery of all precious metals.

Minor Metals & Mineral Conservation an Overview: Part One

During past ten to fifteen years, the chemistry and metallurgy of pure and ultra-pure minor metals (MMs) and their compounds have been better understood.
In the periodic table the elements are arranged in various groups according to their respective physical & chemical properties and termed as: alkali, alkaline earth, transition metals, metalloids etc., but in trade & industries the terminologies like “ferrous / non-ferrous, base / precious, “major / minor” metals are used.
