Abstract: This paper aims to discover the mechanism of removal of arsenic and bismuth from copper electrolyte under the function of antimony.
Although the form condition is different, it can be concluded that the compounds of (Sb, As)2O3, BiSb2O7, SbAsO4 are essential phase in the purification of copper electrolytes.
The mixture of compounds formed and deposited in the solution according to reaction(1) to (4), this leads to the decline of the concentration of As, Sb and Bi in solution, and therefore the impurities of As and Bi are removed from the synthetic electrolytes by Sb.

With an aim to utilize the local-based waste materials, this research investigated the production of mill scale - biomass pellet (MBP) as an alternative charged material for EAF steelmaking.
Utilization of mill scale can be found in many researches, for example, the production of Fe bearing compounds [1] and the production of pellets for smelting processes [2-4].

Thus, the sericulture can produce medical biomaterials both from the cultivation of Bombyx mori such as some bioactive compounds of protein fibers from cocoon namely sericin and fibroin, and other medicinal compounds from pupae and cocoon shells, and from mulberry plants, namely some bioactive compounds from leaves, fruit, as well as stem and root barks.
Mulberry leaves of Morus alba L were detected containing of two bioactive compounds, namely quercetin 3-O-malonylglucoside and kaempferol 3-O-malonylglucoside that were found to be able increase the growth hormone secretion and as a key ingredient for the anti-aging activity [38].
The bioactive compounds containing in silk mulberry plants, Morus alba L as known as white mulberry and Morus nigra as known as black mulberry and the other varieties, can be used in human health, preventively and therapeutically, for instances, anti-oxidant, anti-cancer, anti-diabetic, anti-cholesterol, anti-aging and anti-obesity.
Some bioactive compounds were isolated from the silkworm cocoon shells, for instance, two flavonoids containing the l-proline moiety, 6-C-[(2S,5S)-prolin-5-yl] quercetin (prolinalin A) and 6-C-[(2S,5R)-prolin-5-yl] quercetin (prolinalin B) [47].
A multifunctional hybrid inorganic-organic coating fabricated on magnesium alloy surface with antiplatelet adhesion and antibacterial activities.

This is due to PNPNP additions with changes in the wavenumbers of the observed peaks affirming formation of new compounds due to interactions of the PLA molecules and PNPNP.
The peaks in the XRD results signify some identified compounds.
X-ray diffractogram of the pristine PLA showing some identified compounds Fig. 7.
The difference is linked with identified compounds in the pristine PLA (Figure 6) which are not the same with those detected in the PLA composites.
Variations in the structures of the detected compounds are proposed to contribute to the overall microstructural differences in Figure 9a-b.

The compound is also improved by slow rolling speed and a large roller.
Force values are not comparable due to different final thicknesses of the materials and are not the aim of the tests.
After annealing, a dark layer forms at the boundary between the different alloy areas (Figure 3).

During the process, evaporated metals and metal alloys enter the plasma state to combine with the ionised process gas (nitrogen) and eventually condense on the substrate surface, as part of ceramic compounds.
Ten measurements per each sample were obtained with the aim to have a representative average value.
