Introduction Solder dross was formed during melting process and handling of tin alloys, it floats on the molten bath around 98 % of metallic tin and skimmed manually.
Since the leaching processof Sn oxide using citric acid have not been reported yet, therefore the main aim of this research is to study the new method to recover high percentage of Sn which is economical in waste treatments.
Compound SnO2 NiO CuO ZnO Fe2O3 GeO2 Others Concentration (%) 98.3 0.04 0.69 0.08 0.56 0.14 0.19 The solder dross powder was dissolved in a leaching solution of acid in different concentration (0.1 M, 0.2 M, 0.3 M, 0.5 M, 0.8 M and 1.0 M).

A coating material as powder mixture of the (Al or its alloys), an inert filler material (Al2O3), and a halide activator (NH4Cl) are used in HAPC aluminization [15].
The phases presented in the alloys were recognized by X- ray with General electric diffractomer, of 2o (2Q) per minute scanning speed with CuKa (l = 1.54 À).
Zirconium or zirconium compounds phases, which are likely present in the outer layer in insufficient amounts, are unnoticeable by X-ray diffraction analysis.
According to authors [25, 26], the oxidation process of a commercial Inconel 600 alloy is comparable to that of a Ni-Cr alloy, but following stages reveal a significant difference between the two alloys due to the influence of the small alloying component iron in IN600.

Katsuyoshi et al [3] had presented advanced Cu-40 mass% Zn alloys with high tensile strength and excellent machinability which were developed via a P/M process.
Nanocomposites are conventionally produced by a combination of mechanical alloying and P/M processing.
The production of nanoparticles by milling a combination of powders or compounds to form a new product by a solid-state displacement reaction has received increasing attention in recent years.
These evidences showed that the composites have hardness equivalent to many of commercial copper alloys.

For the wire electrode made of copper or copper alloys (brass) which is a soft material, the machinability coefficient is Kpr <1.
Experimental research performed at the frequency of 40 kHz by ultrasonic activating the wire electrode at two points after two perpendicular directions in space has highlighted the power influence of the ultrasound generator on the amplitude of compound vibration (figure 3).
The monitoring of the process aimed mainly at improving certain technological parameters such as: processing efficiency, volume wear, relative wear, surface quality, but also improving the economic efficiency of processing.
