“…Recently, the sustainable development of advanced material with superior characteristics has been achieved by utilizing waste metal scrap and natural organic sources via low‐cost conventional fabrication increased in several industrial applications like structural doors, windows, trucks, automotive, and vessels. The waste metal scrap was treated by non‐chemical and chemical actions (Flett, 1979; Panayotova, 2017). The composite has two constitutions, major and minor, called matrix and reinforcement.…”

Fabrication industries are emerging to reduce and recycle waste scrap materials into useful products for various engineering applications such as domestic, structural, marine, and construction doors and windows. Most waste scrap materials are affected by soil and water pollution, resulting in unsuitable environmental living. This study is to fabricate the low‐cost and eco‐friendly Al‐ZrO2 alloy composite made with waste Al/Mg metal scrap microparticles through stir casting technique and the developed composite with 0 wt%, 5 wt%, 10 wt%, and 15 wt% of ZrO2 were studied its mechanical properties (ASTM). The synthesized composites' mechanical tensile strength, impact, and hardness were evaluated by ASTM test standard. The revealed experimental results were compared and an optimum sample was addressed. The optical micrograph studies revealed the metal particle presence. The sample 4 composite contained 15 wt% of ZrO2 particles and showed superior mechanical properties like 7.7%, 57.7%, and 13.66% improvement in tensile strength, impact toughness, and hardness compared to sample 1 without ZrO2 particles.

“…The liquid-gel has the advantage of combining the favorable effects of the liquid-liquid extraction and those of the liquid-solid extraction is a technique that can be implemented to solve analytical problems but also to separate and recover metal elements of economic interest (secondary materials), or to preserve the environment, [8][9][10].…”

Abstract. Recent decades, it is an awareness of the importance of ecological balance in the environment, balances threatened by industrial pollution. A new spirit presides we seek to minimize pollution of receiving waters. The present work is to study the liquid-gel-extraction of zinc ions in perchlorate medium by an acid extractant: the di (ethyl-2 hexyl) phosphorique acid, or DEHPA. Two types of polymers were used as supports of solvent extraction: a polybutadiene rubber cross-linked respectively with 0.1% dicumyl peroxide and 0.4% dicumyl peroxide, vulcanized at 160°C, one is most cross-linked than the other. The liquid-gel extraction is based on the principles of the liquid-liquid extraction.

Removal of ethoxylated aliphatic amines from zinc containing effluents by adsorption on macroporous resins

The separation of ethoxylated aliphatic amines from zinc containing effluents with macroporous polymeric adsorbents Wofatit EP 61, EP 62, Y 59, Y 77 and active carbons has been examined. The adsorption behaviour has been investigated as a function of temperature, time and concentration of Na2S04, ZnS04 and H2S04. The macroporous polymers EP 61, Y 77 and Y 59 are capable of separating ethoxylated aliphatic amines from effluents of viscose fibre industry at higher temperatures and under weakly acidic conditions. In contrast to active carbon, inorganic components are not adsorbed on the investigated macroporous resins. Data obtained in a concentration range of 0 to 10 g of adsorbate per litre produced a Langmuir profile for adsorption of ethoxylated aliphatic amines by polymeric adsorbents.

Solvent extraction in scrap and waste processing

Abstract: The role of solvent extraction in the processing of metalliferous scrap and waste is reviewed. Its use is found to be significant and it is likely to play an increasingly important role in the development of scrap and waste reprocessing flowsheets.
