Mutengesi weBenzoyl Hydroximic Acid kuSouth Africa

Chii chinonzi Benzoyl Hydroximic Acid?

Benzoyl hydroximic acid (BHA, benzhydroxamic acid) ndiyo iri nyore kushandisa aromatic hydroxamic acid, ine ring yephenyl (benzene) yakabatana zvakananga ne hydroxamic acid functional group (C(=O)NHOH). Imhando yemuunganidzi we hydroxamic acid yakadzidziswa zvakanyanya, inoshandiswa zvakanyanya mukutsvaga nekuda kwekuchena kwayo kwakanyanya uye chimiro chayo chemorekuru, uye inoshandiswa zvakanyanya semuunganidzi we oxide mineral flotation uko sarudzo yayo inopa mabhenefiti kupfuura alkyl (fatty acid type) hydroxamic acids.

Kusarudza uye Kushanda

BHA inonyanya kusarudza cassiterite (SnO₂), wolframite ((Fe,Mn)WO₄), uye rare earth oxide minerals, zvichigadzira ring chelate complexes dzakagadzikana kwazvo panzvimbo dzadzo dzakapfuma nesimbi ukuwo zvichiratidza kunyudzwa kushoma pa quartz uye akawanda ma silicate gangue minerals. Mu flotation ye tin ne tungsten, BHA inopa kudzoreredzwa kwakanaka kwe target oxide mineral uye kurambwa kwakanaka kwe gangue, zvichideredza zvinodiwa zvekuchenesa concentrate. Kuchena kwayo kwakanyanya kunoita kuti ive yakakodzera kushandiswa kwekutsvaga uko kuchena kwe collector kunodiwa pakudzidza kwe mechanistic.

Ruzivo rweKugovera

Terracore Chemicals inopa benzoyl hydroximic acid mumabhegi anorema 25 kg pamagiredhi ehunyanzvi uye ekutsvagisa. Tinopa mazano ekugadzirisa zvinhu zvakanaka (tembiricha, pH, ethanol/water co-solvent kuti inyunguduke) uye pakuenzanisa sarudzo ne salicyl ne alkyl hydroximic acid collectors kune mamwe ma oxide mineral assemblages.
