1. Corrugated surface corrosion: Spectral analysis revealed that the concentration of non-ferrous metal elements was abnormal. The sub-micron-scale wear particles of many non-ferrous metal components were present in the iron spectrum, and the lubricating oil exceeded the water and the acid value exceeded.
2, the external appearance of the journal: spectral analysis found that the concentration of iron is abnormal; there are many sub-micron particles of iron in the iron spectrum; lubricating oil moisture overrun or acid value overrun.
3, the external appearance of the journal: there are iron-based cutting abrasive black oxide particles in the iron spectrum; metal appearance has tempering color.
4, fretting wear behind the tile: spectral analysis found that the iron concentration is abnormal; there are many iron components in the iron spectrum sub-micron wear particles; lubricating oil moisture and acid value is abnormal.
5, bearing external strain: found in the iron spectrum cutting abrasive; abrasive particles are non-ferrous metals.
6. Wafer surface shedding: There are many large-scale fatigue-shedding alloy wear particles and layered abrasive grains found in the iron spectrum.
7. Bearing burnt tile: There are many large-scale alloy abrasive grains and black metal oxides in the iron spectrum.

Our key products are litharge using in assaying of precious metal, and lead nitrate using in gold mining. Lead nitrate is used as medical astringent; tanning material for leather-making; dyeing mordant; photograph promoting agent; flotation for ore; chemical reagents; and also used for making fireworks, match, and other lead salts. In the mean time, we are sourcing the other chemical reagents for our mining customers in Australia, Canada, Africa etc.

1. Product name:lead nitrate

2. Character: white crystal powder, relative density 4.53(20), easily soluble in water, liquid ammonia, light dissolve in ethyl alcohol, not dissolve in concentrated nitrate acid, solubility 56.5g/100g water (20). Dry lead nitrate decompose at 205-223. Damp lead nitrate decompose at 100, first become Pb(NO3)2 . PbO, go on heating, then become PbO. It is strong oxidant, putting together with organics will lead it burning, noxious.
3. Application: Used as flotation reagent for gold ore and other ore.
